Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491472, here are decompositions:

11 + 491461 = 491472
43 + 491429 = 491472
101 + 491371 = 491472
131 + 491341 = 491472
139 + 491333 = 491472
173 + 491299 = 491472
193 + 491279 = 491472
199 + 491273 = 491472

Showing the first eight; more decompositions exist.
