Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121480, here are decompositions:

11 + 121469 = 121480
41 + 121439 = 121480
59 + 121421 = 121480
101 + 121379 = 121480
113 + 121367 = 121480
131 + 121349 = 121480
137 + 121343 = 121480
167 + 121313 = 121480

Showing the first eight; more decompositions exist.
