Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731256, here are decompositions:

7 + 8731249 = 8731256
43 + 8731213 = 8731256
103 + 8731153 = 8731256
229 + 8731027 = 8731256
307 + 8730949 = 8731256
337 + 8730919 = 8731256
367 + 8730889 = 8731256
397 + 8730859 = 8731256

Showing the first eight; more decompositions exist.
