Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535386, here are decompositions:

5 + 31535381 = 31535386
59 + 31535327 = 31535386
167 + 31535219 = 31535386
173 + 31535213 = 31535386
263 + 31535123 = 31535386
353 + 31535033 = 31535386
587 + 31534799 = 31535386
599 + 31534787 = 31535386

Showing the first eight; more decompositions exist.
