Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613964, here are decompositions:

37 + 31613927 = 31613964
97 + 31613867 = 31613964
103 + 31613861 = 31613964
131 + 31613833 = 31613964
157 + 31613807 = 31613964
163 + 31613801 = 31613964
167 + 31613797 = 31613964
181 + 31613783 = 31613964

Showing the first eight; more decompositions exist.
