Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601530, here are decompositions:

3 + 31601527 = 31601530
17 + 31601513 = 31601530
41 + 31601489 = 31601530
113 + 31601417 = 31601530
137 + 31601393 = 31601530
173 + 31601357 = 31601530
263 + 31601267 = 31601530
431 + 31601099 = 31601530

Showing the first eight; more decompositions exist.
