Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612274, here are decompositions:

73 + 31612201 = 31612274
193 + 31612081 = 31612274
277 + 31611997 = 31612274
367 + 31611907 = 31612274
433 + 31611841 = 31612274
457 + 31611817 = 31612274
541 + 31611733 = 31612274
571 + 31611703 = 31612274

Showing the first eight; more decompositions exist.
