Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536502, here are decompositions:

3 + 31536499 = 31536502
149 + 31536353 = 31536502
401 + 31536101 = 31536502
449 + 31536053 = 31536502
521 + 31535981 = 31536502
563 + 31535939 = 31536502
593 + 31535909 = 31536502
761 + 31535741 = 31536502

Showing the first eight; more decompositions exist.
