Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724308, here are decompositions:

7 + 8724301 = 8724308
67 + 8724241 = 8724308
127 + 8724181 = 8724308
139 + 8724169 = 8724308
181 + 8724127 = 8724308
331 + 8723977 = 8724308
379 + 8723929 = 8724308
409 + 8723899 = 8724308

Showing the first eight; more decompositions exist.
