Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610958, here are decompositions:

47 + 31610911 = 31610958
167 + 31610791 = 31610958
179 + 31610779 = 31610958
229 + 31610729 = 31610958
251 + 31610707 = 31610958
317 + 31610641 = 31610958
389 + 31610569 = 31610958
397 + 31610561 = 31610958

Showing the first eight; more decompositions exist.
