Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450460, here are decompositions:

31 + 31450429 = 31450460
37 + 31450423 = 31450460
73 + 31450387 = 31450460
109 + 31450351 = 31450460
241 + 31450219 = 31450460
367 + 31450093 = 31450460
439 + 31450021 = 31450460
523 + 31449937 = 31450460

Showing the first eight; more decompositions exist.
