Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724398, here are decompositions:

79 + 8724319 = 8724398
97 + 8724301 = 8724398
139 + 8724259 = 8724398
157 + 8724241 = 8724398
229 + 8724169 = 8724398
271 + 8724127 = 8724398
421 + 8723977 = 8724398
499 + 8723899 = 8724398

Showing the first eight; more decompositions exist.
