Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540252, here are decompositions:

11 + 31540241 = 31540252
41 + 31540211 = 31540252
71 + 31540181 = 31540252
89 + 31540163 = 31540252
239 + 31540013 = 31540252
281 + 31539971 = 31540252
389 + 31539863 = 31540252
431 + 31539821 = 31540252

Showing the first eight; more decompositions exist.
