Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613100, here are decompositions:

47 + 31613053 = 31613100
73 + 31613027 = 31613100
109 + 31612991 = 31613100
131 + 31612969 = 31613100
139 + 31612961 = 31613100
149 + 31612951 = 31613100
227 + 31612873 = 31613100
269 + 31612831 = 31613100

Showing the first eight; more decompositions exist.
