Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491284, here are decompositions:

5 + 491279 = 491284
11 + 491273 = 491284
23 + 491261 = 491284
71 + 491213 = 491284
83 + 491201 = 491284
113 + 491171 = 491284
281 + 491003 = 491284
293 + 490991 = 491284

Showing the first eight; more decompositions exist.
