Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558348, here are decompositions:

11 + 31558337 = 31558348
137 + 31558211 = 31558348
149 + 31558199 = 31558348
167 + 31558181 = 31558348
179 + 31558169 = 31558348
389 + 31557959 = 31558348
467 + 31557881 = 31558348
491 + 31557857 = 31558348

Showing the first eight; more decompositions exist.
