Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491626, here are decompositions:

89 + 491537 = 491626
137 + 491489 = 491626
197 + 491429 = 491626
269 + 491357 = 491626
293 + 491333 = 491626
347 + 491279 = 491626
353 + 491273 = 491626
467 + 491159 = 491626

Showing the first eight; more decompositions exist.
