Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558116, here are decompositions:

43 + 31558073 = 31558116
53 + 31558063 = 31558116
59 + 31558057 = 31558116
67 + 31558049 = 31558116
97 + 31558019 = 31558116
103 + 31558013 = 31558116
157 + 31557959 = 31558116
179 + 31557937 = 31558116

Showing the first eight; more decompositions exist.
