Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566674, here are decompositions:

43 + 31566631 = 31566674
127 + 31566547 = 31566674
151 + 31566523 = 31566674
157 + 31566517 = 31566674
193 + 31566481 = 31566674
277 + 31566397 = 31566674
523 + 31566151 = 31566674
613 + 31566061 = 31566674

Showing the first eight; more decompositions exist.
