Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601768, here are decompositions:

61 + 31601707 = 31601768
97 + 31601671 = 31601768
139 + 31601629 = 31601768
199 + 31601569 = 31601768
229 + 31601539 = 31601768
241 + 31601527 = 31601768
409 + 31601359 = 31601768
421 + 31601347 = 31601768

Showing the first eight; more decompositions exist.
