Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521774, here are decompositions:

7 + 521767 = 521774
31 + 521743 = 521774
67 + 521707 = 521774
103 + 521671 = 521774
193 + 521581 = 521774
223 + 521551 = 521774
241 + 521533 = 521774
271 + 521503 = 521774

Showing the first eight; more decompositions exist.
