Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542946, here are decompositions:

3 + 31542943 = 31542946
5 + 31542941 = 31542946
89 + 31542857 = 31542946
137 + 31542809 = 31542946
179 + 31542767 = 31542946
269 + 31542677 = 31542946
359 + 31542587 = 31542946
467 + 31542479 = 31542946

Showing the first eight; more decompositions exist.
