Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610774, here are decompositions:

3 + 31610771 = 31610774
67 + 31610707 = 31610774
193 + 31610581 = 31610774
211 + 31610563 = 31610774
271 + 31610503 = 31610774
337 + 31610437 = 31610774
421 + 31610353 = 31610774
457 + 31610317 = 31610774

Showing the first eight; more decompositions exist.
