Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540606, here are decompositions:

107 + 31540499 = 31540606
113 + 31540493 = 31540606
263 + 31540343 = 31540606
389 + 31540217 = 31540606
443 + 31540163 = 31540606
593 + 31540013 = 31540606
599 + 31540007 = 31540606
743 + 31539863 = 31540606

Showing the first eight; more decompositions exist.
