Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491546, here are decompositions:

7 + 491539 = 491546
19 + 491527 = 491546
43 + 491503 = 491546
193 + 491353 = 491546
379 + 491167 = 491546
397 + 491149 = 491546
409 + 491137 = 491546
463 + 491083 = 491546

Showing the first eight; more decompositions exist.
