Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627534, here are decompositions:

23 + 31627511 = 31627534
317 + 31627217 = 31627534
383 + 31627151 = 31627534
401 + 31627133 = 31627534
443 + 31627091 = 31627534
461 + 31627073 = 31627534
557 + 31626977 = 31627534
641 + 31626893 = 31627534

Showing the first eight; more decompositions exist.
