Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540506, here are decompositions:

5 + 31540501 = 31540506
7 + 31540499 = 31540506
13 + 31540493 = 31540506
17 + 31540489 = 31540506
89 + 31540417 = 31540506
163 + 31540343 = 31540506
167 + 31540339 = 31540506
197 + 31540309 = 31540506

Showing the first eight; more decompositions exist.
