Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540084, here are decompositions:

53 + 31540031 = 31540084
71 + 31540013 = 31540084
113 + 31539971 = 31540084
227 + 31539857 = 31540084
263 + 31539821 = 31540084
347 + 31539737 = 31540084
491 + 31539593 = 31540084
617 + 31539467 = 31540084

Showing the first eight; more decompositions exist.
