Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502978, here are decompositions:

5 + 502973 = 502978
17 + 502961 = 502978
41 + 502937 = 502978
59 + 502919 = 502978
131 + 502847 = 502978
137 + 502841 = 502978
149 + 502829 = 502978
191 + 502787 = 502978

Showing the first eight; more decompositions exist.
