Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540264, here are decompositions:

3 + 31540261 = 31540264
23 + 31540241 = 31540264
47 + 31540217 = 31540264
53 + 31540211 = 31540264
83 + 31540181 = 31540264
101 + 31540163 = 31540264
233 + 31540031 = 31540264
251 + 31540013 = 31540264

Showing the first eight; more decompositions exist.
