Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501142, here are decompositions:

3 + 501139 = 501142
11 + 501131 = 501142
53 + 501089 = 501142
113 + 501029 = 501142
233 + 500909 = 501142
251 + 500891 = 501142
269 + 500873 = 501142
281 + 500861 = 501142

Showing the first eight; more decompositions exist.
