Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723380, here are decompositions:

59 + 8723321 = 8723380
137 + 8723243 = 8723380
167 + 8723213 = 8723380
257 + 8723123 = 8723380
317 + 8723063 = 8723380
389 + 8722991 = 8723380
431 + 8722949 = 8723380
467 + 8722913 = 8723380

Showing the first eight; more decompositions exist.
