Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535582, here are decompositions:

31 + 31535551 = 31535582
79 + 31535503 = 31535582
163 + 31535419 = 31535582
241 + 31535341 = 31535582
271 + 31535311 = 31535582
349 + 31535233 = 31535582
409 + 31535173 = 31535582
439 + 31535143 = 31535582

Showing the first eight; more decompositions exist.
