Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723630, here are decompositions:

37 + 8723593 = 8723630
61 + 8723569 = 8723630
79 + 8723551 = 8723630
109 + 8723521 = 8723630
151 + 8723479 = 8723630
193 + 8723437 = 8723630
211 + 8723419 = 8723630
271 + 8723359 = 8723630

Showing the first eight; more decompositions exist.
