Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491418, here are decompositions:

41 + 491377 = 491418
47 + 491371 = 491418
61 + 491357 = 491418
79 + 491339 = 491418
89 + 491329 = 491418
139 + 491279 = 491418
157 + 491261 = 491418
167 + 491251 = 491418

Showing the first eight; more decompositions exist.
