Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450484, here are decompositions:

61 + 31450423 = 31450484
73 + 31450411 = 31450484
97 + 31450387 = 31450484
193 + 31450291 = 31450484
277 + 31450207 = 31450484
367 + 31450117 = 31450484
463 + 31450021 = 31450484
547 + 31449937 = 31450484

Showing the first eight; more decompositions exist.
