Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543294, here are decompositions:

71 + 31543223 = 31543294
113 + 31543181 = 31543294
131 + 31543163 = 31543294
191 + 31543103 = 31543294
227 + 31543067 = 31543294
353 + 31542941 = 31543294
383 + 31542911 = 31543294
467 + 31542827 = 31543294

Showing the first eight; more decompositions exist.
