Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731132, here are decompositions:

23 + 8731109 = 8731132
29 + 8731103 = 8731132
101 + 8731031 = 8731132
149 + 8730983 = 8731132
239 + 8730893 = 8731132
251 + 8730881 = 8731132
269 + 8730863 = 8731132
281 + 8730851 = 8731132

Showing the first eight; more decompositions exist.
