Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476626, here are decompositions:

3 + 31476623 = 31476626
19 + 31476607 = 31476626
79 + 31476547 = 31476626
109 + 31476517 = 31476626
127 + 31476499 = 31476626
193 + 31476433 = 31476626
277 + 31476349 = 31476626
283 + 31476343 = 31476626

Showing the first eight; more decompositions exist.
