Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723672, here are decompositions:

19 + 8723653 = 8723672
79 + 8723593 = 8723672
103 + 8723569 = 8723672
151 + 8723521 = 8723672
193 + 8723479 = 8723672
313 + 8723359 = 8723672
523 + 8723149 = 8723672
619 + 8723053 = 8723672

Showing the first eight; more decompositions exist.
