Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627276, here are decompositions:

29 + 31627247 = 31627276
59 + 31627217 = 31627276
269 + 31627007 = 31627276
383 + 31626893 = 31627276
419 + 31626857 = 31627276
449 + 31626827 = 31627276
479 + 31626797 = 31627276
509 + 31626767 = 31627276

Showing the first eight; more decompositions exist.
