Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601402, here are decompositions:

43 + 31601359 = 31601402
61 + 31601341 = 31601402
139 + 31601263 = 31601402
199 + 31601203 = 31601402
211 + 31601191 = 31601402
223 + 31601179 = 31601402
379 + 31601023 = 31601402
409 + 31600993 = 31601402

Showing the first eight; more decompositions exist.
