Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503730, here are decompositions:

13 + 503717 = 503730
23 + 503707 = 503730
67 + 503663 = 503730
83 + 503647 = 503730
107 + 503623 = 503730
109 + 503621 = 503730
131 + 503599 = 503730
137 + 503593 = 503730

Showing the first eight; more decompositions exist.
