Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535436, here are decompositions:

7 + 31535429 = 31535436
13 + 31535423 = 31535436
17 + 31535419 = 31535436
19 + 31535417 = 31535436
59 + 31535377 = 31535436
109 + 31535327 = 31535436
173 + 31535263 = 31535436
223 + 31535213 = 31535436

Showing the first eight; more decompositions exist.
