Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601382, here are decompositions:

23 + 31601359 = 31601382
41 + 31601341 = 31601382
179 + 31601203 = 31601382
191 + 31601191 = 31601382
283 + 31601099 = 31601382
331 + 31601051 = 31601382
359 + 31601023 = 31601382
389 + 31600993 = 31601382

Showing the first eight; more decompositions exist.
