Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610360, here are decompositions:

7 + 31610353 = 31610360
43 + 31610317 = 31610360
73 + 31610287 = 31610360
163 + 31610197 = 31610360
277 + 31610083 = 31610360
337 + 31610023 = 31610360
349 + 31610011 = 31610360
367 + 31609993 = 31610360

Showing the first eight; more decompositions exist.
