Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731152, here are decompositions:

11 + 8731141 = 8731152
13 + 8731139 = 8731152
41 + 8731111 = 8731152
43 + 8731109 = 8731152
83 + 8731069 = 8731152
113 + 8731039 = 8731152
223 + 8730929 = 8731152
233 + 8730919 = 8731152

Showing the first eight; more decompositions exist.
