Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627594, here are decompositions:

17 + 31627577 = 31627594
83 + 31627511 = 31627594
347 + 31627247 = 31627594
443 + 31627151 = 31627594
461 + 31627133 = 31627594
503 + 31627091 = 31627594
521 + 31627073 = 31627594
587 + 31627007 = 31627594

Showing the first eight; more decompositions exist.
