Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147553278, here are decompositions:

  • 97 + 2147553181 = 2147553278
  • 127 + 2147553151 = 2147553278
  • 229 + 2147553049 = 2147553278
  • 331 + 2147552947 = 2147553278
  • 457 + 2147552821 = 2147553278
  • 547 + 2147552731 = 2147553278
  • 601 + 2147552677 = 2147553278
  • 691 + 2147552587 = 2147553278

Showing the first eight; more decompositions exist.
