Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491268, here are decompositions:

7 + 491261 = 491268
17 + 491251 = 491268
67 + 491201 = 491268
97 + 491171 = 491268
101 + 491167 = 491268
109 + 491159 = 491268
131 + 491137 = 491268
139 + 491129 = 491268

Showing the first eight; more decompositions exist.
