Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601346, here are decompositions:

5 + 31601341 = 31601346
79 + 31601267 = 31601346
83 + 31601263 = 31601346
167 + 31601179 = 31601346
263 + 31601083 = 31601346
269 + 31601077 = 31601346
353 + 31600993 = 31601346
389 + 31600957 = 31601346

Showing the first eight; more decompositions exist.
