Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461710, here are decompositions:

13 + 31461697 = 31461710
37 + 31461673 = 31461710
139 + 31461571 = 31461710
157 + 31461553 = 31461710
193 + 31461517 = 31461710
223 + 31461487 = 31461710
229 + 31461481 = 31461710
283 + 31461427 = 31461710

Showing the first eight; more decompositions exist.
