Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502578, here are decompositions:

29 + 502549 = 502578
61 + 502517 = 502578
71 + 502507 = 502578
79 + 502499 = 502578
127 + 502451 = 502578
137 + 502441 = 502578
149 + 502429 = 502578
157 + 502421 = 502578

Showing the first eight; more decompositions exist.
