Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542226, here are decompositions:

29 + 31542197 = 31542226
113 + 31542113 = 31542226
293 + 31541933 = 31542226
593 + 31541633 = 31542226
719 + 31541507 = 31542226
743 + 31541483 = 31542226
797 + 31541429 = 31542226
809 + 31541417 = 31542226

Showing the first eight; more decompositions exist.
