Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613300, here are decompositions:

73 + 31613227 = 31613300
109 + 31613191 = 31613300
157 + 31613143 = 31613300
163 + 31613137 = 31613300
181 + 31613119 = 31613300
193 + 31613107 = 31613300
331 + 31612969 = 31613300
349 + 31612951 = 31613300

Showing the first eight; more decompositions exist.
