Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742464, here are decompositions:

43 + 8742421 = 8742464
97 + 8742367 = 8742464
151 + 8742313 = 8742464
271 + 8742193 = 8742464
277 + 8742187 = 8742464
307 + 8742157 = 8742464
331 + 8742133 = 8742464
397 + 8742067 = 8742464

Showing the first eight; more decompositions exist.
