Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538904, here are decompositions:

103 + 538801 = 538904
127 + 538777 = 538904
181 + 538723 = 538904
193 + 538711 = 538904
283 + 538621 = 538904
307 + 538597 = 538904
337 + 538567 = 538904
433 + 538471 = 538904

Showing the first eight; more decompositions exist.
