Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627424, here are decompositions:

13 + 31627411 = 31627424
67 + 31627357 = 31627424
163 + 31627261 = 31627424
181 + 31627243 = 31627424
223 + 31627201 = 31627424
373 + 31627051 = 31627424
397 + 31627027 = 31627424
457 + 31626967 = 31627424

Showing the first eight; more decompositions exist.
