Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535682, here are decompositions:

11 + 31535671 = 31535682
43 + 31535639 = 31535682
89 + 31535593 = 31535682
131 + 31535551 = 31535682
179 + 31535503 = 31535682
263 + 31535419 = 31535682
271 + 31535411 = 31535682
419 + 31535263 = 31535682

Showing the first eight; more decompositions exist.
