Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610434, here are decompositions:

41 + 31610393 = 31610434
71 + 31610363 = 31610434
101 + 31610333 = 31610434
197 + 31610237 = 31610434
263 + 31610171 = 31610434
293 + 31610141 = 31610434
353 + 31610081 = 31610434
461 + 31609973 = 31610434

Showing the first eight; more decompositions exist.
