Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627340, here are decompositions:

7 + 31627333 = 31627340
37 + 31627303 = 31627340
79 + 31627261 = 31627340
97 + 31627243 = 31627340
103 + 31627237 = 31627340
139 + 31627201 = 31627340
271 + 31627069 = 31627340
307 + 31627033 = 31627340

Showing the first eight; more decompositions exist.
