Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601256, here are decompositions:

53 + 31601203 = 31601256
157 + 31601099 = 31601256
173 + 31601083 = 31601256
179 + 31601077 = 31601256
233 + 31601023 = 31601256
263 + 31600993 = 31601256
373 + 31600883 = 31601256
397 + 31600859 = 31601256

Showing the first eight; more decompositions exist.
