Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610370, here are decompositions:

7 + 31610363 = 31610370
17 + 31610353 = 31610370
31 + 31610339 = 31610370
37 + 31610333 = 31610370
53 + 31610317 = 31610370
79 + 31610291 = 31610370
83 + 31610287 = 31610370
101 + 31610269 = 31610370

Showing the first eight; more decompositions exist.
