Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610858, here are decompositions:

67 + 31610791 = 31610858
79 + 31610779 = 31610858
151 + 31610707 = 31610858
229 + 31610629 = 31610858
271 + 31610587 = 31610858
277 + 31610581 = 31610858
337 + 31610521 = 31610858
421 + 31610437 = 31610858

Showing the first eight; more decompositions exist.
