Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450534, here are decompositions:

47 + 31450487 = 31450534
83 + 31450451 = 31450534
107 + 31450427 = 31450534
113 + 31450421 = 31450534
263 + 31450271 = 31450534
317 + 31450217 = 31450534
431 + 31450103 = 31450534
491 + 31450043 = 31450534

Showing the first eight; more decompositions exist.
