Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510890, here are decompositions:

43 + 510847 = 510890
67 + 510823 = 510890
73 + 510817 = 510890
97 + 510793 = 510890
139 + 510751 = 510890
181 + 510709 = 510890
199 + 510691 = 510890
271 + 510619 = 510890

Showing the first eight; more decompositions exist.
