Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535590, here are decompositions:

41 + 31535549 = 31535590
167 + 31535423 = 31535590
173 + 31535417 = 31535590
179 + 31535411 = 31535590
263 + 31535327 = 31535590
269 + 31535321 = 31535590
419 + 31535171 = 31535590
467 + 31535123 = 31535590

Showing the first eight; more decompositions exist.
