Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537426, here are decompositions:

17 + 31537409 = 31537426
113 + 31537313 = 31537426
197 + 31537229 = 31537426
293 + 31537133 = 31537426
383 + 31537043 = 31537426
443 + 31536983 = 31537426
467 + 31536959 = 31537426
509 + 31536917 = 31537426

Showing the first eight; more decompositions exist.
