Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613106, here are decompositions:

53 + 31613053 = 31613106
79 + 31613027 = 31613106
137 + 31612969 = 31613106
167 + 31612939 = 31613106
193 + 31612913 = 31613106
233 + 31612873 = 31613106
347 + 31612759 = 31613106
353 + 31612753 = 31613106

Showing the first eight; more decompositions exist.
