Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503840, here are decompositions:

13 + 503827 = 503840
19 + 503821 = 503840
37 + 503803 = 503840
61 + 503779 = 503840
97 + 503743 = 503840
193 + 503647 = 503840
229 + 503611 = 503840
241 + 503599 = 503840

Showing the first eight; more decompositions exist.
