Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731044, here are decompositions:

5 + 8731039 = 8731044
13 + 8731031 = 8731044
17 + 8731027 = 8731044
61 + 8730983 = 8731044
67 + 8730977 = 8731044
97 + 8730947 = 8731044
131 + 8730913 = 8731044
151 + 8730893 = 8731044

Showing the first eight; more decompositions exist.
