Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537468, here are decompositions:

59 + 31537409 = 31537468
197 + 31537271 = 31537468
239 + 31537229 = 31537468
317 + 31537151 = 31537468
419 + 31537049 = 31537468
467 + 31537001 = 31537468
509 + 31536959 = 31537468
647 + 31536821 = 31537468

Showing the first eight; more decompositions exist.
