Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534502, here are decompositions:

19 + 31534483 = 31534502
61 + 31534441 = 31534502
73 + 31534429 = 31534502
79 + 31534423 = 31534502
271 + 31534231 = 31534502
523 + 31533979 = 31534502
631 + 31533871 = 31534502
673 + 31533829 = 31534502

Showing the first eight; more decompositions exist.
