Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612300, here are decompositions:

23 + 31612277 = 31612300
59 + 31612241 = 31612300
101 + 31612199 = 31612300
149 + 31612151 = 31612300
179 + 31612121 = 31612300
191 + 31612109 = 31612300
257 + 31612043 = 31612300
359 + 31611941 = 31612300

Showing the first eight; more decompositions exist.
