Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612260, here are decompositions:

19 + 31612241 = 31612260
37 + 31612223 = 31612260
59 + 31612201 = 31612260
61 + 31612199 = 31612260
109 + 31612151 = 31612260
139 + 31612121 = 31612260
151 + 31612109 = 31612260
179 + 31612081 = 31612260

Showing the first eight; more decompositions exist.
