Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540796, here are decompositions:

13 + 31540783 = 31540796
73 + 31540723 = 31540796
97 + 31540699 = 31540796
103 + 31540693 = 31540796
127 + 31540669 = 31540796
139 + 31540657 = 31540796
223 + 31540573 = 31540796
307 + 31540489 = 31540796

Showing the first eight; more decompositions exist.
