Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730740, here are decompositions:

3 + 8730737 = 8730740
43 + 8730697 = 8730740
79 + 8730661 = 8730740
157 + 8730583 = 8730740
163 + 8730577 = 8730740
181 + 8730559 = 8730740
211 + 8730529 = 8730740
223 + 8730517 = 8730740

Showing the first eight; more decompositions exist.
