Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723788, here are decompositions:

149 + 8723639 = 8723788
179 + 8723609 = 8723788
257 + 8723531 = 8723788
347 + 8723441 = 8723788
389 + 8723399 = 8723788
401 + 8723387 = 8723788
467 + 8723321 = 8723788
797 + 8722991 = 8723788

Showing the first eight; more decompositions exist.
