Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601406, here are decompositions:

13 + 31601393 = 31601406
47 + 31601359 = 31601406
59 + 31601347 = 31601406
139 + 31601267 = 31601406
227 + 31601179 = 31601406
269 + 31601137 = 31601406
307 + 31601099 = 31601406
383 + 31601023 = 31601406

Showing the first eight; more decompositions exist.
