Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731144, here are decompositions:

3 + 8731141 = 8731144
5 + 8731139 = 8731144
41 + 8731103 = 8731144
47 + 8731097 = 8731144
113 + 8731031 = 8731144
167 + 8730977 = 8731144
197 + 8730947 = 8731144
251 + 8730893 = 8731144

Showing the first eight; more decompositions exist.
