Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724020, here are decompositions:

7 + 8724013 = 8724020
43 + 8723977 = 8724020
73 + 8723947 = 8724020
127 + 8723893 = 8724020
199 + 8723821 = 8724020
313 + 8723707 = 8724020
367 + 8723653 = 8724020
499 + 8723521 = 8724020

Showing the first eight; more decompositions exist.
