Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540770, here are decompositions:

43 + 31540727 = 31540770
47 + 31540723 = 31540770
61 + 31540709 = 31540770
71 + 31540699 = 31540770
101 + 31540669 = 31540770
113 + 31540657 = 31540770
127 + 31540643 = 31540770
139 + 31540631 = 31540770

Showing the first eight; more decompositions exist.
