Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476746, here are decompositions:

3 + 31476743 = 31476746
13 + 31476733 = 31476746
19 + 31476727 = 31476746
43 + 31476703 = 31476746
139 + 31476607 = 31476746
199 + 31476547 = 31476746
229 + 31476517 = 31476746
313 + 31476433 = 31476746

Showing the first eight; more decompositions exist.
