Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491532, here are decompositions:

5 + 491527 = 491532
29 + 491503 = 491532
31 + 491501 = 491532
43 + 491489 = 491532
71 + 491461 = 491532
103 + 491429 = 491532
109 + 491423 = 491532
179 + 491353 = 491532

Showing the first eight; more decompositions exist.
