Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566692, here are decompositions:

61 + 31566631 = 31566692
103 + 31566589 = 31566692
151 + 31566541 = 31566692
211 + 31566481 = 31566692
523 + 31566169 = 31566692
541 + 31566151 = 31566692
613 + 31566079 = 31566692
631 + 31566061 = 31566692

Showing the first eight; more decompositions exist.
