Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535636, here are decompositions:

3 + 31535633 = 31535636
43 + 31535593 = 31535636
373 + 31535263 = 31535636
409 + 31535227 = 31535636
463 + 31535173 = 31535636
523 + 31535113 = 31535636
577 + 31535059 = 31535636
757 + 31534879 = 31535636

Showing the first eight; more decompositions exist.
