Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79280, here are decompositions:

7 + 79273 = 79280
79 + 79201 = 79280
127 + 79153 = 79280
193 + 79087 = 79280
241 + 79039 = 79280
379 + 78901 = 79280
457 + 78823 = 79280
499 + 78781 = 79280

Showing the first eight; more decompositions exist.
