Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601548, here are decompositions:

59 + 31601489 = 31601548
131 + 31601417 = 31601548
137 + 31601411 = 31601548
191 + 31601357 = 31601548
281 + 31601267 = 31601548
449 + 31601099 = 31601548
827 + 31600721 = 31601548
929 + 31600619 = 31601548

Showing the first eight; more decompositions exist.
