Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627268, here are decompositions:

7 + 31627261 = 31627268
19 + 31627249 = 31627268
31 + 31627237 = 31627268
67 + 31627201 = 31627268
199 + 31627069 = 31627268
241 + 31627027 = 31627268
577 + 31626691 = 31627268
601 + 31626667 = 31627268

Showing the first eight; more decompositions exist.
