Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499520, here are decompositions:

13 + 499507 = 499520
37 + 499483 = 499520
61 + 499459 = 499520
97 + 499423 = 499520
157 + 499363 = 499520
193 + 499327 = 499520
199 + 499321 = 499520
211 + 499309 = 499520

Showing the first eight; more decompositions exist.
