Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535510, here are decompositions:

7 + 31535503 = 31535510
43 + 31535467 = 31535510
199 + 31535311 = 31535510
277 + 31535233 = 31535510
283 + 31535227 = 31535510
337 + 31535173 = 31535510
367 + 31535143 = 31535510
379 + 31535131 = 31535510

Showing the first eight; more decompositions exist.
