Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601418, here are decompositions:

7 + 31601411 = 31601418
11 + 31601407 = 31601418
59 + 31601359 = 31601418
61 + 31601357 = 31601418
71 + 31601347 = 31601418
151 + 31601267 = 31601418
227 + 31601191 = 31601418
239 + 31601179 = 31601418

Showing the first eight; more decompositions exist.
