Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502144, here are decompositions:

3 + 502141 = 502144
11 + 502133 = 502144
23 + 502121 = 502144
101 + 502043 = 502144
131 + 502013 = 502144
173 + 501971 = 502144
191 + 501953 = 502144
197 + 501947 = 502144

Showing the first eight; more decompositions exist.
