Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520202, here are decompositions:

73 + 520129 = 520202
79 + 520123 = 520202
139 + 520063 = 520202
181 + 520021 = 520202
271 + 519931 = 520202
283 + 519919 = 520202
313 + 519889 = 520202
409 + 519793 = 520202

Showing the first eight; more decompositions exist.
