Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535466, here are decompositions:

37 + 31535429 = 31535466
43 + 31535423 = 31535466
47 + 31535419 = 31535466
89 + 31535377 = 31535466
139 + 31535327 = 31535466
233 + 31535233 = 31535466
239 + 31535227 = 31535466
283 + 31535183 = 31535466

Showing the first eight; more decompositions exist.
