Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624492, here are decompositions:

  • 149 + 31624343 = 31624492
  • 479 + 31624013 = 31624492
  • 491 + 31624001 = 31624492
  • 503 + 31623989 = 31624492
  • 509 + 31623983 = 31624492
  • 521 + 31623971 = 31624492
  • 563 + 31623929 = 31624492
  • 761 + 31623731 = 31624492

Showing the first eight; more decompositions exist.
