Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537674, here are decompositions:

43 + 31537631 = 31537674
71 + 31537603 = 31537674
83 + 31537591 = 31537674
101 + 31537573 = 31537674
127 + 31537547 = 31537674
131 + 31537543 = 31537674
167 + 31537507 = 31537674
193 + 31537481 = 31537674

Showing the first eight; more decompositions exist.
