Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450036, here are decompositions:

3 + 31450033 = 31450036
5 + 31450031 = 31450036
47 + 31449989 = 31450036
113 + 31449923 = 31450036
269 + 31449767 = 31450036
347 + 31449689 = 31450036
389 + 31449647 = 31450036
467 + 31449569 = 31450036

Showing the first eight; more decompositions exist.
