Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502142, here are decompositions:

61 + 502081 = 502142
79 + 502063 = 502142
103 + 502039 = 502142
211 + 501931 = 502142
313 + 501829 = 502142
373 + 501769 = 502142
439 + 501703 = 502142
541 + 501601 = 502142

Showing the first eight; more decompositions exist.
