Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500232, here are decompositions:

  • 11 + 31500221 = 31500232
  • 83 + 31500149 = 31500232
  • 131 + 31500101 = 31500232
  • 149 + 31500083 = 31500232
  • 293 + 31499939 = 31500232
  • 311 + 31499921 = 31500232
  • 389 + 31499843 = 31500232
  • 521 + 31499711 = 31500232

Showing the first eight; more decompositions exist.
