Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627364, here are decompositions:

7 + 31627357 = 31627364
31 + 31627333 = 31627364
61 + 31627303 = 31627364
103 + 31627261 = 31627364
127 + 31627237 = 31627364
163 + 31627201 = 31627364
313 + 31627051 = 31627364
331 + 31627033 = 31627364

Showing the first eight; more decompositions exist.
