Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540426, here are decompositions:

37 + 540389 = 540426
43 + 540383 = 540426
53 + 540373 = 540426
59 + 540367 = 540426
79 + 540347 = 540426
83 + 540343 = 540426
157 + 540269 = 540426
193 + 540233 = 540426

Showing the first eight; more decompositions exist.
