Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535522, here are decompositions:

19 + 31535503 = 31535522
103 + 31535419 = 31535522
181 + 31535341 = 31535522
211 + 31535311 = 31535522
349 + 31535173 = 31535522
379 + 31535143 = 31535522
409 + 31535113 = 31535522
439 + 31535083 = 31535522

Showing the first eight; more decompositions exist.
