Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491434, here are decompositions:

5 + 491429 = 491434
11 + 491423 = 491434
17 + 491417 = 491434
101 + 491333 = 491434
107 + 491327 = 491434
137 + 491297 = 491434
173 + 491261 = 491434
233 + 491201 = 491434

Showing the first eight; more decompositions exist.
