Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566482, here are decompositions:

193 + 31566289 = 31566482
313 + 31566169 = 31566482
331 + 31566151 = 31566482
421 + 31566061 = 31566482
439 + 31566043 = 31566482
463 + 31566019 = 31566482
613 + 31565869 = 31566482
631 + 31565851 = 31566482

Showing the first eight; more decompositions exist.
