Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112780, here are decompositions:

23 + 112757 = 112780
89 + 112691 = 112780
137 + 112643 = 112780
179 + 112601 = 112780
191 + 112589 = 112780
197 + 112583 = 112780
383 + 112397 = 112780
419 + 112361 = 112780

Showing the first eight; more decompositions exist.
