Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529102, here are decompositions:

  • 13 + 31529089 = 31529102
  • 109 + 31528993 = 31529102
  • 193 + 31528909 = 31529102
  • 271 + 31528831 = 31529102
  • 373 + 31528729 = 31529102
  • 379 + 31528723 = 31529102
  • 433 + 31528669 = 31529102
  • 523 + 31528579 = 31529102

Showing the first eight; more decompositions exist.
