Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601444, here are decompositions:

37 + 31601407 = 31601444
97 + 31601347 = 31601444
103 + 31601341 = 31601444
181 + 31601263 = 31601444
241 + 31601203 = 31601444
307 + 31601137 = 31601444
367 + 31601077 = 31601444
421 + 31601023 = 31601444

Showing the first eight; more decompositions exist.
