Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463558, here are decompositions:

31 + 31463527 = 31463558
151 + 31463407 = 31463558
229 + 31463329 = 31463558
241 + 31463317 = 31463558
277 + 31463281 = 31463558
331 + 31463227 = 31463558
397 + 31463161 = 31463558
421 + 31463137 = 31463558

Showing the first eight; more decompositions exist.
