Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723902, here are decompositions:

3 + 8723899 = 8723902
23 + 8723879 = 8723902
113 + 8723789 = 8723902
263 + 8723639 = 8723902
293 + 8723609 = 8723902
419 + 8723483 = 8723902
443 + 8723459 = 8723902
461 + 8723441 = 8723902

Showing the first eight; more decompositions exist.
