Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612004, here are decompositions:

7 + 31611997 = 31612004
97 + 31611907 = 31612004
163 + 31611841 = 31612004
271 + 31611733 = 31612004
331 + 31611673 = 31612004
337 + 31611667 = 31612004
397 + 31611607 = 31612004
421 + 31611583 = 31612004

Showing the first eight; more decompositions exist.
