Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535702, here are decompositions:

31 + 31535671 = 31535702
109 + 31535593 = 31535702
151 + 31535551 = 31535702
199 + 31535503 = 31535702
283 + 31535419 = 31535702
439 + 31535263 = 31535702
571 + 31535131 = 31535702
619 + 31535083 = 31535702

Showing the first eight; more decompositions exist.
