Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610494, here are decompositions:

101 + 31610393 = 31610494
131 + 31610363 = 31610494
257 + 31610237 = 31610494
263 + 31610231 = 31610494
281 + 31610213 = 31610494
353 + 31610141 = 31610494
401 + 31610093 = 31610494
431 + 31610063 = 31610494

Showing the first eight; more decompositions exist.
