Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483532, here are decompositions:

61 + 31483471 = 31483532
79 + 31483453 = 31483532
103 + 31483429 = 31483532
163 + 31483369 = 31483532
181 + 31483351 = 31483532
271 + 31483261 = 31483532
439 + 31483093 = 31483532
463 + 31483069 = 31483532

Showing the first eight; more decompositions exist.
