Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723738, here are decompositions:

7 + 8723731 = 8723738
31 + 8723707 = 8723738
61 + 8723677 = 8723738
241 + 8723497 = 8723738
379 + 8723359 = 8723738
421 + 8723317 = 8723738
547 + 8723191 = 8723738
601 + 8723137 = 8723738

Showing the first eight; more decompositions exist.
