Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535652, here are decompositions:

13 + 31535639 = 31535652
19 + 31535633 = 31535652
59 + 31535593 = 31535652
61 + 31535591 = 31535652
101 + 31535551 = 31535652
103 + 31535549 = 31535652
149 + 31535503 = 31535652
223 + 31535429 = 31535652

Showing the first eight; more decompositions exist.
