Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601262, here are decompositions:

59 + 31601203 = 31601262
71 + 31601191 = 31601262
83 + 31601179 = 31601262
163 + 31601099 = 31601262
179 + 31601083 = 31601262
211 + 31601051 = 31601262
239 + 31601023 = 31601262
269 + 31600993 = 31601262

Showing the first eight; more decompositions exist.
