Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723746, here are decompositions:

107 + 8723639 = 8723746
137 + 8723609 = 8723746
263 + 8723483 = 8723746
347 + 8723399 = 8723746
359 + 8723387 = 8723746
443 + 8723303 = 8723746
503 + 8723243 = 8723746
683 + 8723063 = 8723746

Showing the first eight; more decompositions exist.
