Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610654, here are decompositions:

13 + 31610641 = 31610654
67 + 31610587 = 31610654
73 + 31610581 = 31610654
151 + 31610503 = 31610654
241 + 31610413 = 31610654
337 + 31610317 = 31610654
367 + 31610287 = 31610654
457 + 31610197 = 31610654

Showing the first eight; more decompositions exist.
