Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542366, here are decompositions:

7 + 31542359 = 31542366
43 + 31542323 = 31542366
137 + 31542229 = 31542366
263 + 31542103 = 31542366
283 + 31542083 = 31542366
353 + 31542013 = 31542366
389 + 31541977 = 31542366
433 + 31541933 = 31542366

Showing the first eight; more decompositions exist.
