Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521630, here are decompositions:

73 + 521557 = 521630
79 + 521551 = 521630
97 + 521533 = 521630
103 + 521527 = 521630
127 + 521503 = 521630
139 + 521491 = 521630
229 + 521401 = 521630
271 + 521359 = 521630

Showing the first eight; more decompositions exist.
