Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535628, here are decompositions:

37 + 31535591 = 31535628
79 + 31535549 = 31535628
199 + 31535429 = 31535628
211 + 31535417 = 31535628
251 + 31535377 = 31535628
307 + 31535321 = 31535628
317 + 31535311 = 31535628
401 + 31535227 = 31535628

Showing the first eight; more decompositions exist.
