Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723538, here are decompositions:

7 + 8723531 = 8723538
17 + 8723521 = 8723538
41 + 8723497 = 8723538
59 + 8723479 = 8723538
79 + 8723459 = 8723538
97 + 8723441 = 8723538
101 + 8723437 = 8723538
139 + 8723399 = 8723538

Showing the first eight; more decompositions exist.
