Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483632, here are decompositions:

79 + 31483553 = 31483632
83 + 31483549 = 31483632
139 + 31483493 = 31483632
163 + 31483469 = 31483632
179 + 31483453 = 31483632
199 + 31483433 = 31483632
241 + 31483391 = 31483632
263 + 31483369 = 31483632

Showing the first eight; more decompositions exist.
