Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535426, here are decompositions:

3 + 31535423 = 31535426
7 + 31535419 = 31535426
163 + 31535263 = 31535426
193 + 31535233 = 31535426
199 + 31535227 = 31535426
283 + 31535143 = 31535426
313 + 31535113 = 31535426
367 + 31535059 = 31535426

Showing the first eight; more decompositions exist.
