Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540062, here are decompositions:

31 + 31540031 = 31540062
53 + 31540009 = 31540062
131 + 31539931 = 31540062
173 + 31539889 = 31540062
199 + 31539863 = 31540062
223 + 31539839 = 31540062
241 + 31539821 = 31540062
349 + 31539713 = 31540062

Showing the first eight; more decompositions exist.
