Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611974, here are decompositions:

67 + 31611907 = 31611974
157 + 31611817 = 31611974
241 + 31611733 = 31611974
271 + 31611703 = 31611974
307 + 31611667 = 31611974
367 + 31611607 = 31611974
397 + 31611577 = 31611974
421 + 31611553 = 31611974

Showing the first eight; more decompositions exist.
