Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540380, here are decompositions:

3 + 540377 = 540380
7 + 540373 = 540380
13 + 540367 = 540380
31 + 540349 = 540380
37 + 540343 = 540380
73 + 540307 = 540380
79 + 540301 = 540380
97 + 540283 = 540380

Showing the first eight; more decompositions exist.
