Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147580394, here are decompositions:

  • 17 + 2147580377 = 2147580394
  • 173 + 2147580221 = 2147580394
  • 257 + 2147580137 = 2147580394
  • 293 + 2147580101 = 2147580394
  • 347 + 2147580047 = 2147580394
  • 461 + 2147579933 = 2147580394
  • 587 + 2147579807 = 2147580394
  • 653 + 2147579741 = 2147580394

Showing the first eight; more decompositions exist.
