Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527450, here are decompositions:

  • 37 + 31527413 = 31527450
  • 43 + 31527407 = 31527450
  • 61 + 31527389 = 31527450
  • 107 + 31527343 = 31527450
  • 127 + 31527323 = 31527450
  • 139 + 31527311 = 31527450
  • 173 + 31527277 = 31527450
  • 197 + 31527253 = 31527450

Showing the first eight; more decompositions exist.
