Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510872, here are decompositions:

79 + 510793 = 510872
163 + 510709 = 510872
181 + 510691 = 510872
283 + 510589 = 510872
409 + 510463 = 510872
421 + 510451 = 510872
541 + 510331 = 510872
601 + 510271 = 510872

Showing the first eight; more decompositions exist.
