Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483526, here are decompositions:

73 + 31483453 = 31483526
79 + 31483447 = 31483526
97 + 31483429 = 31483526
157 + 31483369 = 31483526
199 + 31483327 = 31483526
313 + 31483213 = 31483526
409 + 31483117 = 31483526
433 + 31483093 = 31483526

Showing the first eight; more decompositions exist.
