Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601454, here are decompositions:

37 + 31601417 = 31601454
43 + 31601411 = 31601454
47 + 31601407 = 31601454
61 + 31601393 = 31601454
97 + 31601357 = 31601454
107 + 31601347 = 31601454
113 + 31601341 = 31601454
191 + 31601263 = 31601454

Showing the first eight; more decompositions exist.
