Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610458, here are decompositions:

167 + 31610291 = 31610458
179 + 31610279 = 31610458
227 + 31610231 = 31610458
317 + 31610141 = 31610458
419 + 31610039 = 31610458
449 + 31610009 = 31610458
491 + 31609967 = 31610458
521 + 31609937 = 31610458

Showing the first eight; more decompositions exist.
