Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491924, here are decompositions:

67 + 491857 = 491924
73 + 491851 = 491924
127 + 491797 = 491924
151 + 491773 = 491924
193 + 491731 = 491924
271 + 491653 = 491924
313 + 491611 = 491924
331 + 491593 = 491924

Showing the first eight; more decompositions exist.
