Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731208, here are decompositions:

7 + 8731201 = 8731208
67 + 8731141 = 8731208
97 + 8731111 = 8731208
139 + 8731069 = 8731208
181 + 8731027 = 8731208
307 + 8730901 = 8731208
349 + 8730859 = 8731208
547 + 8730661 = 8731208

Showing the first eight; more decompositions exist.
