Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542196, here are decompositions:

47 + 31542149 = 31542196
83 + 31542113 = 31542196
113 + 31542083 = 31542196
173 + 31542023 = 31542196
263 + 31541933 = 31542196
293 + 31541903 = 31542196
503 + 31541693 = 31542196
563 + 31541633 = 31542196

Showing the first eight; more decompositions exist.
