Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731446, here are decompositions:

13 + 8731433 = 8731446
19 + 8731427 = 8731446
29 + 8731417 = 8731446
83 + 8731363 = 8731446
103 + 8731343 = 8731446
107 + 8731339 = 8731446
137 + 8731309 = 8731446
197 + 8731249 = 8731446

Showing the first eight; more decompositions exist.
