Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601456, here are decompositions:

97 + 31601359 = 31601456
109 + 31601347 = 31601456
193 + 31601263 = 31601456
277 + 31601179 = 31601456
373 + 31601083 = 31601456
379 + 31601077 = 31601456
433 + 31601023 = 31601456
463 + 31600993 = 31601456

Showing the first eight; more decompositions exist.
