Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535026, here are decompositions:

113 + 31534913 = 31535026
227 + 31534799 = 31535026
239 + 31534787 = 31535026
269 + 31534757 = 31535026
317 + 31534709 = 31535026
389 + 31534637 = 31535026
569 + 31534457 = 31535026
599 + 31534427 = 31535026

Showing the first eight; more decompositions exist.
