Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503786, here are decompositions:

7 + 503779 = 503786
43 + 503743 = 503786
79 + 503707 = 503786
139 + 503647 = 503786
163 + 503623 = 503786
193 + 503593 = 503786
223 + 503563 = 503786
373 + 503413 = 503786

Showing the first eight; more decompositions exist.
