Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567832, here are decompositions:

13 + 31567819 = 31567832
19 + 31567813 = 31567832
103 + 31567729 = 31567832
139 + 31567693 = 31567832
151 + 31567681 = 31567832
211 + 31567621 = 31567832
229 + 31567603 = 31567832
421 + 31567411 = 31567832

Showing the first eight; more decompositions exist.
