Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627338, here are decompositions:

5 + 31627333 = 31627338
19 + 31627319 = 31627338
89 + 31627249 = 31627338
101 + 31627237 = 31627338
137 + 31627201 = 31627338
269 + 31627069 = 31627338
311 + 31627027 = 31627338
331 + 31627007 = 31627338

Showing the first eight; more decompositions exist.
