Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558546, here are decompositions:

17 + 31558529 = 31558546
83 + 31558463 = 31558546
113 + 31558433 = 31558546
167 + 31558379 = 31558546
263 + 31558283 = 31558546
293 + 31558253 = 31558546
317 + 31558229 = 31558546
347 + 31558199 = 31558546

Showing the first eight; more decompositions exist.
