Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540142, here are decompositions:

3 + 540139 = 540142
23 + 540119 = 540142
41 + 540101 = 540142
101 + 540041 = 540142
149 + 539993 = 540142
293 + 539849 = 540142
359 + 539783 = 540142
419 + 539723 = 540142

Showing the first eight; more decompositions exist.
