Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81674, here are decompositions:

3 + 81671 = 81674
7 + 81667 = 81674
37 + 81637 = 81674
127 + 81547 = 81674
157 + 81517 = 81674
211 + 81463 = 81674
331 + 81343 = 81674
367 + 81307 = 81674

Showing the first eight; more decompositions exist.
