Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503780, here are decompositions:

3 + 503777 = 503780
37 + 503743 = 503780
73 + 503707 = 503780
127 + 503653 = 503780
157 + 503623 = 503780
181 + 503599 = 503780
229 + 503551 = 503780
349 + 503431 = 503780

Showing the first eight; more decompositions exist.
