Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461704, here are decompositions:

7 + 31461697 = 31461704
31 + 31461673 = 31461704
151 + 31461553 = 31461704
181 + 31461523 = 31461704
223 + 31461481 = 31461704
277 + 31461427 = 31461704
523 + 31461181 = 31461704
541 + 31461163 = 31461704

Showing the first eight; more decompositions exist.
