Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521472, here are decompositions:

43 + 521429 = 521472
71 + 521401 = 521472
73 + 521399 = 521472
79 + 521393 = 521472
103 + 521369 = 521472
109 + 521363 = 521472
113 + 521359 = 521472
163 + 521309 = 521472

Showing the first eight; more decompositions exist.
