Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731038, here are decompositions:

7 + 8731031 = 8731038
11 + 8731027 = 8731038
61 + 8730977 = 8731038
89 + 8730949 = 8731038
109 + 8730929 = 8731038
137 + 8730901 = 8731038
149 + 8730889 = 8731038
157 + 8730881 = 8731038

Showing the first eight; more decompositions exist.
