Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724368, here are decompositions:

67 + 8724301 = 8724368
109 + 8724259 = 8724368
127 + 8724241 = 8724368
199 + 8724169 = 8724368
229 + 8724139 = 8724368
241 + 8724127 = 8724368
421 + 8723947 = 8724368
439 + 8723929 = 8724368

Showing the first eight; more decompositions exist.
