Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540742, here are decompositions:

29 + 540713 = 540742
53 + 540689 = 540742
113 + 540629 = 540742
131 + 540611 = 540742
233 + 540509 = 540742
281 + 540461 = 540742
353 + 540389 = 540742
359 + 540383 = 540742

Showing the first eight; more decompositions exist.
