Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535606, here are decompositions:

13 + 31535593 = 31535606
103 + 31535503 = 31535606
139 + 31535467 = 31535606
229 + 31535377 = 31535606
373 + 31535233 = 31535606
379 + 31535227 = 31535606
433 + 31535173 = 31535606
463 + 31535143 = 31535606

Showing the first eight; more decompositions exist.
