Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491026, here are decompositions:

23 + 491003 = 491026
59 + 490967 = 491026
89 + 490937 = 491026
113 + 490913 = 491026
149 + 490877 = 491026
167 + 490859 = 491026
197 + 490829 = 491026
257 + 490769 = 491026

Showing the first eight; more decompositions exist.
