Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540676, here are decompositions:

7 + 31540669 = 31540676
19 + 31540657 = 31540676
103 + 31540573 = 31540676
313 + 31540363 = 31540676
337 + 31540339 = 31540676
367 + 31540309 = 31540676
379 + 31540297 = 31540676
463 + 31540213 = 31540676

Showing the first eight; more decompositions exist.
