Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43780, here are decompositions:

3 + 43777 = 43780
59 + 43721 = 43780
89 + 43691 = 43780
131 + 43649 = 43780
167 + 43613 = 43780
173 + 43607 = 43780
239 + 43541 = 43780
263 + 43517 = 43780

Showing the first eight; more decompositions exist.
