Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610862, here are decompositions:

71 + 31610791 = 31610862
83 + 31610779 = 31610862
89 + 31610773 = 31610862
139 + 31610723 = 31610862
223 + 31610639 = 31610862
233 + 31610629 = 31610862
281 + 31610581 = 31610862
293 + 31610569 = 31610862

Showing the first eight; more decompositions exist.
