Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723580, here are decompositions:

11 + 8723569 = 8723580
29 + 8723551 = 8723580
59 + 8723521 = 8723580
83 + 8723497 = 8723580
97 + 8723483 = 8723580
101 + 8723479 = 8723580
139 + 8723441 = 8723580
157 + 8723423 = 8723580

Showing the first eight; more decompositions exist.
