Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478462, here are decompositions:

61 + 31478401 = 31478462
73 + 31478389 = 31478462
139 + 31478323 = 31478462
283 + 31478179 = 31478462
373 + 31478089 = 31478462
439 + 31478023 = 31478462
709 + 31477753 = 31478462
733 + 31477729 = 31478462

Showing the first eight; more decompositions exist.
