Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479536, here are decompositions:

19 + 31479517 = 31479536
37 + 31479499 = 31479536
79 + 31479457 = 31479536
97 + 31479439 = 31479536
199 + 31479337 = 31479536
229 + 31479307 = 31479536
409 + 31479127 = 31479536
463 + 31479073 = 31479536

Showing the first eight; more decompositions exist.
