Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611848, here are decompositions:

7 + 31611841 = 31611848
19 + 31611829 = 31611848
31 + 31611817 = 31611848
139 + 31611709 = 31611848
181 + 31611667 = 31611848
241 + 31611607 = 31611848
271 + 31611577 = 31611848
409 + 31611439 = 31611848

Showing the first eight; more decompositions exist.
