Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731300, here are decompositions:

23 + 8731277 = 8731300
89 + 8731211 = 8731300
113 + 8731187 = 8731300
191 + 8731109 = 8731300
197 + 8731103 = 8731300
269 + 8731031 = 8731300
317 + 8730983 = 8731300
353 + 8730947 = 8731300

Showing the first eight; more decompositions exist.
