Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540066, here are decompositions:

3 + 31540063 = 31540066
53 + 31540013 = 31540066
59 + 31540007 = 31540066
227 + 31539839 = 31540066
353 + 31539713 = 31540066
359 + 31539707 = 31540066
479 + 31539587 = 31540066
599 + 31539467 = 31540066

Showing the first eight; more decompositions exist.
