Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497390, here are decompositions:

  • 29 + 2147497361 = 2147497390
  • 41 + 2147497349 = 2147497390
  • 257 + 2147497133 = 2147497390
  • 347 + 2147497043 = 2147497390
  • 419 + 2147496971 = 2147497390
  • 449 + 2147496941 = 2147497390
  • 659 + 2147496731 = 2147497390
  • 677 + 2147496713 = 2147497390

Showing the first eight; more decompositions exist.
