Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611704, here are decompositions:

31 + 31611673 = 31611704
37 + 31611667 = 31611704
97 + 31611607 = 31611704
127 + 31611577 = 31611704
151 + 31611553 = 31611704
337 + 31611367 = 31611704
433 + 31611271 = 31611704
541 + 31611163 = 31611704

Showing the first eight; more decompositions exist.
