Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540478, here are decompositions:

17 + 540461 = 540478
41 + 540437 = 540478
89 + 540389 = 540478
101 + 540377 = 540478
131 + 540347 = 540478
227 + 540251 = 540478
311 + 540167 = 540478
359 + 540119 = 540478

Showing the first eight; more decompositions exist.
