Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552432, here are decompositions:

  • 3 + 31552429 = 31552432
  • 11 + 31552421 = 31552432
  • 29 + 31552403 = 31552432
  • 179 + 31552253 = 31552432
  • 239 + 31552193 = 31552432
  • 293 + 31552139 = 31552432
  • 383 + 31552049 = 31552432
  • 491 + 31551941 = 31552432

Showing the first eight; more decompositions exist.
