Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747442, here are decompositions:

19 + 8747423 = 8747442
23 + 8747419 = 8747442
61 + 8747381 = 8747442
113 + 8747329 = 8747442
181 + 8747261 = 8747442
191 + 8747251 = 8747442
199 + 8747243 = 8747442
229 + 8747213 = 8747442

Showing the first eight; more decompositions exist.
