Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535806, here are decompositions:

53 + 31535753 = 31535806
59 + 31535747 = 31535806
89 + 31535717 = 31535806
149 + 31535657 = 31535806
167 + 31535639 = 31535806
173 + 31535633 = 31535806
257 + 31535549 = 31535806
383 + 31535423 = 31535806

Showing the first eight; more decompositions exist.
