Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501488, here are decompositions:

37 + 501451 = 501488
61 + 501427 = 501488
79 + 501409 = 501488
271 + 501217 = 501488
331 + 501157 = 501488
349 + 501139 = 501488
367 + 501121 = 501488
457 + 501031 = 501488

Showing the first eight; more decompositions exist.
