Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491152, here are decompositions:

3 + 491149 = 491152
23 + 491129 = 491152
71 + 491081 = 491152
113 + 491039 = 491152
149 + 491003 = 491152
239 + 490913 = 491152
293 + 490859 = 491152
383 + 490769 = 491152

Showing the first eight; more decompositions exist.
