Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501890, here are decompositions:

61 + 501829 = 501890
73 + 501817 = 501890
199 + 501691 = 501890
313 + 501577 = 501890
379 + 501511 = 501890
397 + 501493 = 501890
439 + 501451 = 501890
463 + 501427 = 501890

Showing the first eight; more decompositions exist.
