Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583284, here are decompositions:

  • 3 + 31583281 = 31583284
  • 113 + 31583171 = 31583284
  • 137 + 31583147 = 31583284
  • 197 + 31583087 = 31583284
  • 233 + 31583051 = 31583284
  • 251 + 31583033 = 31583284
  • 347 + 31582937 = 31583284
  • 353 + 31582931 = 31583284

Showing the first eight; more decompositions exist.
