Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610888, here are decompositions:

97 + 31610791 = 31610888
109 + 31610779 = 31610888
181 + 31610707 = 31610888
307 + 31610581 = 31610888
349 + 31610539 = 31610888
367 + 31610521 = 31610888
499 + 31610389 = 31610888
571 + 31610317 = 31610888

Showing the first eight; more decompositions exist.
