Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723768, here are decompositions:

37 + 8723731 = 8723768
61 + 8723707 = 8723768
199 + 8723569 = 8723768
271 + 8723497 = 8723768
331 + 8723437 = 8723768
349 + 8723419 = 8723768
409 + 8723359 = 8723768
421 + 8723347 = 8723768

Showing the first eight; more decompositions exist.
