Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601466, here are decompositions:

59 + 31601407 = 31601466
73 + 31601393 = 31601466
107 + 31601359 = 31601466
109 + 31601357 = 31601466
199 + 31601267 = 31601466
263 + 31601203 = 31601466
367 + 31601099 = 31601466
383 + 31601083 = 31601466

Showing the first eight; more decompositions exist.
