Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540574, here are decompositions:

17 + 540557 = 540574
113 + 540461 = 540574
137 + 540437 = 540574
191 + 540383 = 540574
197 + 540377 = 540574
227 + 540347 = 540574
401 + 540173 = 540574
653 + 539921 = 540574

Showing the first eight; more decompositions exist.
