Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613292, here are decompositions:

43 + 31613249 = 31613292
101 + 31613191 = 31613292
149 + 31613143 = 31613292
173 + 31613119 = 31613292
239 + 31613053 = 31613292
311 + 31612981 = 31613292
331 + 31612961 = 31613292
353 + 31612939 = 31613292

Showing the first eight; more decompositions exist.
