Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724098, here are decompositions:

151 + 8723947 = 8724098
199 + 8723899 = 8724098
211 + 8723887 = 8724098
277 + 8723821 = 8724098
367 + 8723731 = 8724098
421 + 8723677 = 8724098
547 + 8723551 = 8724098
577 + 8723521 = 8724098

Showing the first eight; more decompositions exist.
