Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89780, here are decompositions:

13 + 89767 = 89780
109 + 89671 = 89780
127 + 89653 = 89780
181 + 89599 = 89780
331 + 89449 = 89780
337 + 89443 = 89780
349 + 89431 = 89780
367 + 89413 = 89780

Showing the first eight; more decompositions exist.
