Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611370, here are decompositions:

3 + 31611367 = 31611370
29 + 31611341 = 31611370
41 + 31611329 = 31611370
47 + 31611323 = 31611370
59 + 31611311 = 31611370
71 + 31611299 = 31611370
233 + 31611137 = 31611370
257 + 31611113 = 31611370

Showing the first eight; more decompositions exist.
