Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723908, here are decompositions:

5 + 8723903 = 8723908
29 + 8723879 = 8723908
101 + 8723807 = 8723908
269 + 8723639 = 8723908
449 + 8723459 = 8723908
467 + 8723441 = 8723908
509 + 8723399 = 8723908
521 + 8723387 = 8723908

Showing the first eight; more decompositions exist.
