Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463156, here are decompositions:

19 + 31463137 = 31463156
73 + 31463083 = 31463156
79 + 31463077 = 31463156
223 + 31462933 = 31463156
349 + 31462807 = 31463156
397 + 31462759 = 31463156
409 + 31462747 = 31463156
433 + 31462723 = 31463156

Showing the first eight; more decompositions exist.
