Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483564, here are decompositions:

11 + 31483553 = 31483564
17 + 31483547 = 31483564
71 + 31483493 = 31483564
107 + 31483457 = 31483564
131 + 31483433 = 31483564
173 + 31483391 = 31483564
251 + 31483313 = 31483564
257 + 31483307 = 31483564

Showing the first eight; more decompositions exist.
