Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537594, here are decompositions:

3 + 31537591 = 31537594
47 + 31537547 = 31537594
113 + 31537481 = 31537594
281 + 31537313 = 31537594
443 + 31537151 = 31537594
461 + 31537133 = 31537594
467 + 31537127 = 31537594
593 + 31537001 = 31537594

Showing the first eight; more decompositions exist.
