Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491102, here are decompositions:

19 + 491083 = 491102
43 + 491059 = 491102
61 + 491041 = 491102
109 + 490993 = 491102
151 + 490951 = 491102
181 + 490921 = 491102
211 + 490891 = 491102
331 + 490771 = 491102

Showing the first eight; more decompositions exist.
