Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79540, here are decompositions:

3 + 79537 = 79540
47 + 79493 = 79540
59 + 79481 = 79540
89 + 79451 = 79540
107 + 79433 = 79540
113 + 79427 = 79540
173 + 79367 = 79540
191 + 79349 = 79540

Showing the first eight; more decompositions exist.
