Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503900, here are decompositions:

31 + 503869 = 503900
43 + 503857 = 503900
73 + 503827 = 503900
79 + 503821 = 503900
97 + 503803 = 503900
109 + 503791 = 503900
157 + 503743 = 503900
193 + 503707 = 503900

Showing the first eight; more decompositions exist.
