Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516042, here are decompositions:

19 + 516023 = 516042
73 + 515969 = 516042
101 + 515941 = 516042
113 + 515929 = 516042
181 + 515861 = 516042
199 + 515843 = 516042
229 + 515813 = 516042
239 + 515803 = 516042

Showing the first eight; more decompositions exist.
