Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503618, here are decompositions:

7 + 503611 = 503618
19 + 503599 = 503618
67 + 503551 = 503618
211 + 503407 = 503618
229 + 503389 = 503618
331 + 503287 = 503618
421 + 503197 = 503618
487 + 503131 = 503618

Showing the first eight; more decompositions exist.
