Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612148, here are decompositions:

67 + 31612081 = 31612148
79 + 31612069 = 31612148
151 + 31611997 = 31612148
241 + 31611907 = 31612148
307 + 31611841 = 31612148
331 + 31611817 = 31612148
439 + 31611709 = 31612148
541 + 31611607 = 31612148

Showing the first eight; more decompositions exist.
