Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535176, here are decompositions:

3 + 31535173 = 31535176
5 + 31535171 = 31535176
53 + 31535123 = 31535176
263 + 31534913 = 31535176
389 + 31534787 = 31535176
419 + 31534757 = 31535176
467 + 31534709 = 31535176
587 + 31534589 = 31535176

Showing the first eight; more decompositions exist.
