Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535630, here are decompositions:

37 + 31535593 = 31535630
79 + 31535551 = 31535630
127 + 31535503 = 31535630
163 + 31535467 = 31535630
211 + 31535419 = 31535630
367 + 31535263 = 31535630
397 + 31535233 = 31535630
457 + 31535173 = 31535630

Showing the first eight; more decompositions exist.
