Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536998, here are decompositions:

7 + 31536991 = 31536998
61 + 31536937 = 31536998
127 + 31536871 = 31536998
151 + 31536847 = 31536998
499 + 31536499 = 31536998
601 + 31536397 = 31536998
607 + 31536391 = 31536998
811 + 31536187 = 31536998

Showing the first eight; more decompositions exist.
