Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483630, here are decompositions:

47 + 31483583 = 31483630
53 + 31483577 = 31483630
83 + 31483547 = 31483630
137 + 31483493 = 31483630
173 + 31483457 = 31483630
197 + 31483433 = 31483630
239 + 31483391 = 31483630
317 + 31483313 = 31483630

Showing the first eight; more decompositions exist.
