Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491242, here are decompositions:

23 + 491219 = 491242
29 + 491213 = 491242
41 + 491201 = 491242
71 + 491171 = 491242
83 + 491159 = 491242
113 + 491129 = 491242
239 + 491003 = 491242
251 + 490991 = 491242

Showing the first eight; more decompositions exist.
