Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476536, here are decompositions:

19 + 31476517 = 31476536
37 + 31476499 = 31476536
79 + 31476457 = 31476536
103 + 31476433 = 31476536
163 + 31476373 = 31476536
193 + 31476343 = 31476536
349 + 31476187 = 31476536
367 + 31476169 = 31476536

Showing the first eight; more decompositions exist.
