Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491080, here are decompositions:

41 + 491039 = 491080
89 + 490991 = 491080
113 + 490967 = 491080
131 + 490949 = 491080
167 + 490913 = 491080
251 + 490829 = 491080
311 + 490769 = 491080
347 + 490733 = 491080

Showing the first eight; more decompositions exist.
