Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461656, here are decompositions:

3 + 31461653 = 31461656
103 + 31461553 = 31461656
139 + 31461517 = 31461656
199 + 31461457 = 31461656
229 + 31461427 = 31461656
307 + 31461349 = 31461656
313 + 31461343 = 31461656
433 + 31461223 = 31461656

Showing the first eight; more decompositions exist.
