Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724008, here are decompositions:

31 + 8723977 = 8724008
61 + 8723947 = 8724008
79 + 8723929 = 8724008
109 + 8723899 = 8724008
157 + 8723851 = 8724008
277 + 8723731 = 8724008
331 + 8723677 = 8724008
439 + 8723569 = 8724008

Showing the first eight; more decompositions exist.
