Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540422, here are decompositions:

5 + 31540417 = 31540422
59 + 31540363 = 31540422
79 + 31540343 = 31540422
83 + 31540339 = 31540422
113 + 31540309 = 31540422
181 + 31540241 = 31540422
211 + 31540211 = 31540422
233 + 31540189 = 31540422

Showing the first eight; more decompositions exist.
