Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156480, here are decompositions:

13 + 156467 = 156480
43 + 156437 = 156480
59 + 156421 = 156480
61 + 156419 = 156480
109 + 156371 = 156480
127 + 156353 = 156480
151 + 156329 = 156480
173 + 156307 = 156480

Showing the first eight; more decompositions exist.
