Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489248, here are decompositions:

  • 5 + 31489243 = 31489248
  • 19 + 31489229 = 31489248
  • 31 + 31489217 = 31489248
  • 67 + 31489181 = 31489248
  • 71 + 31489177 = 31489248
  • 79 + 31489169 = 31489248
  • 101 + 31489147 = 31489248
  • 151 + 31489097 = 31489248

Showing the first eight; more decompositions exist.
