Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723460, here are decompositions:

19 + 8723441 = 8723460
23 + 8723437 = 8723460
37 + 8723423 = 8723460
41 + 8723419 = 8723460
61 + 8723399 = 8723460
73 + 8723387 = 8723460
101 + 8723359 = 8723460
107 + 8723353 = 8723460

Showing the first eight; more decompositions exist.
