Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535906, here are decompositions:

79 + 31535827 = 31535906
97 + 31535809 = 31535906
109 + 31535797 = 31535906
313 + 31535593 = 31535906
439 + 31535467 = 31535906
487 + 31535419 = 31535906
643 + 31535263 = 31535906
673 + 31535233 = 31535906

Showing the first eight; more decompositions exist.
