Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491030, here are decompositions:

37 + 490993 = 491030
61 + 490969 = 491030
73 + 490957 = 491030
79 + 490951 = 491030
103 + 490927 = 491030
109 + 490921 = 491030
139 + 490891 = 491030
181 + 490849 = 491030

Showing the first eight; more decompositions exist.
