Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540126, here are decompositions:

3 + 31540123 = 31540126
17 + 31540109 = 31540126
113 + 31540013 = 31540126
263 + 31539863 = 31540126
269 + 31539857 = 31540126
389 + 31539737 = 31540126
419 + 31539707 = 31540126
467 + 31539659 = 31540126

Showing the first eight; more decompositions exist.
