Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606508, here are decompositions:

79 + 31606429 = 31606508
97 + 31606411 = 31606508
127 + 31606381 = 31606508
139 + 31606369 = 31606508
211 + 31606297 = 31606508
229 + 31606279 = 31606508
421 + 31606087 = 31606508
457 + 31606051 = 31606508

Showing the first eight; more decompositions exist.
