Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730684, here are decompositions:

23 + 8730661 = 8730684
73 + 8730611 = 8730684
101 + 8730583 = 8730684
107 + 8730577 = 8730684
167 + 8730517 = 8730684
173 + 8730511 = 8730684
197 + 8730487 = 8730684
211 + 8730473 = 8730684

Showing the first eight; more decompositions exist.
