Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540106, here are decompositions:

7 + 31540099 = 31540106
43 + 31540063 = 31540106
97 + 31540009 = 31540106
139 + 31539967 = 31540106
349 + 31539757 = 31540106
379 + 31539727 = 31540106
457 + 31539649 = 31540106
463 + 31539643 = 31540106

Showing the first eight; more decompositions exist.
