Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627262, here are decompositions:

13 + 31627249 = 31627262
19 + 31627243 = 31627262
61 + 31627201 = 31627262
193 + 31627069 = 31627262
211 + 31627051 = 31627262
229 + 31627033 = 31627262
283 + 31626979 = 31627262
379 + 31626883 = 31627262

Showing the first eight; more decompositions exist.
