Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002492, here are decompositions:

5 + 1002487 = 1002492
11 + 1002481 = 1002492
41 + 1002451 = 1002492
59 + 1002433 = 1002492
89 + 1002403 = 1002492
131 + 1002361 = 1002492
149 + 1002343 = 1002492
151 + 1002341 = 1002492

Showing the first eight; more decompositions exist.
