Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611410, here are decompositions:

7 + 31611403 = 31611410
31 + 31611379 = 31611410
43 + 31611367 = 31611410
109 + 31611301 = 31611410
139 + 31611271 = 31611410
223 + 31611187 = 31611410
283 + 31611127 = 31611410
367 + 31611043 = 31611410

Showing the first eight; more decompositions exist.
