Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450846, here are decompositions:

3 + 31450843 = 31450846
5 + 31450841 = 31450846
17 + 31450829 = 31450846
23 + 31450823 = 31450846
59 + 31450787 = 31450846
83 + 31450763 = 31450846
107 + 31450739 = 31450846
179 + 31450667 = 31450846

Showing the first eight; more decompositions exist.
