Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731148, here are decompositions:

7 + 8731141 = 8731148
37 + 8731111 = 8731148
79 + 8731069 = 8731148
109 + 8731039 = 8731148
199 + 8730949 = 8731148
229 + 8730919 = 8731148
367 + 8730781 = 8731148
457 + 8730691 = 8731148

Showing the first eight; more decompositions exist.
