Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520250, here are decompositions:

37 + 520213 = 520250
127 + 520123 = 520250
139 + 520111 = 520250
229 + 520021 = 520250
307 + 519943 = 520250
331 + 519919 = 520250
433 + 519817 = 520250
457 + 519793 = 520250

Showing the first eight; more decompositions exist.
