Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625094, here are decompositions:

37 + 31625057 = 31625094
167 + 31624927 = 31625094
173 + 31624921 = 31625094
233 + 31624861 = 31625094
257 + 31624837 = 31625094
311 + 31624783 = 31625094
313 + 31624781 = 31625094
331 + 31624763 = 31625094

Showing the first eight; more decompositions exist.
