Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483570, here are decompositions:

17 + 31483553 = 31483570
23 + 31483547 = 31483570
101 + 31483469 = 31483570
113 + 31483457 = 31483570
137 + 31483433 = 31483570
179 + 31483391 = 31483570
257 + 31483313 = 31483570
263 + 31483307 = 31483570

Showing the first eight; more decompositions exist.
