Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105480, here are decompositions:

13 + 105467 = 105480
31 + 105449 = 105480
43 + 105437 = 105480
73 + 105407 = 105480
79 + 105401 = 105480
83 + 105397 = 105480
101 + 105379 = 105480
107 + 105373 = 105480

Showing the first eight; more decompositions exist.
