Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535462, here are decompositions:

43 + 31535419 = 31535462
151 + 31535311 = 31535462
199 + 31535263 = 31535462
229 + 31535233 = 31535462
331 + 31535131 = 31535462
349 + 31535113 = 31535462
379 + 31535083 = 31535462
463 + 31534999 = 31535462

Showing the first eight; more decompositions exist.
