Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491502, here are decompositions:

5 + 491497 = 491502
13 + 491489 = 491502
19 + 491483 = 491502
41 + 491461 = 491502
73 + 491429 = 491502
79 + 491423 = 491502
131 + 491371 = 491502
149 + 491353 = 491502

Showing the first eight; more decompositions exist.
