Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723502, here are decompositions:

5 + 8723497 = 8723502
19 + 8723483 = 8723502
23 + 8723479 = 8723502
43 + 8723459 = 8723502
61 + 8723441 = 8723502
79 + 8723423 = 8723502
83 + 8723419 = 8723502
103 + 8723399 = 8723502

Showing the first eight; more decompositions exist.
