Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542214, here are decompositions:

17 + 31542197 = 31542214
101 + 31542113 = 31542214
131 + 31542083 = 31542214
191 + 31542023 = 31542214
233 + 31541981 = 31542214
281 + 31541933 = 31542214
311 + 31541903 = 31542214
521 + 31541693 = 31542214

Showing the first eight; more decompositions exist.
