Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540044, here are decompositions:

13 + 31540031 = 31540044
31 + 31540013 = 31540044
37 + 31540007 = 31540044
73 + 31539971 = 31540044
113 + 31539931 = 31540044
181 + 31539863 = 31540044
223 + 31539821 = 31540044
227 + 31539817 = 31540044

Showing the first eight; more decompositions exist.
