Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536694, here are decompositions:

173 + 31536521 = 31536694
311 + 31536383 = 31536694
347 + 31536347 = 31536694
401 + 31536293 = 31536694
467 + 31536227 = 31536694
491 + 31536203 = 31536694
593 + 31536101 = 31536694
641 + 31536053 = 31536694

Showing the first eight; more decompositions exist.
