Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620382, here are decompositions:

23 + 31620359 = 31620382
83 + 31620299 = 31620382
113 + 31620269 = 31620382
173 + 31620209 = 31620382
179 + 31620203 = 31620382
191 + 31620191 = 31620382
251 + 31620131 = 31620382
389 + 31619993 = 31620382

Showing the first eight; more decompositions exist.
