Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742476, here are decompositions:

7 + 8742469 = 8742476
13 + 8742463 = 8742476
97 + 8742379 = 8742476
109 + 8742367 = 8742476
163 + 8742313 = 8742476
283 + 8742193 = 8742476
307 + 8742169 = 8742476
373 + 8742103 = 8742476

Showing the first eight; more decompositions exist.
