Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521282, here are decompositions:

31 + 521251 = 521282
103 + 521179 = 521282
109 + 521173 = 521282
163 + 521119 = 521282
241 + 521041 = 521282
313 + 520969 = 521282
523 + 520759 = 521282
661 + 520621 = 521282

Showing the first eight; more decompositions exist.
