Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503524, here are decompositions:

  • 163 + 31503361 = 31503524
  • 181 + 31503343 = 31503524
  • 193 + 31503331 = 31503524
  • 211 + 31503313 = 31503524
  • 307 + 31503217 = 31503524
  • 373 + 31503151 = 31503524
  • 421 + 31503103 = 31503524
  • 463 + 31503061 = 31503524

Showing the first eight; more decompositions exist.
