Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761442, here are decompositions:

3 + 8761439 = 8761442
13 + 8761429 = 8761442
103 + 8761339 = 8761442
139 + 8761303 = 8761442
163 + 8761279 = 8761442
199 + 8761243 = 8761442
229 + 8761213 = 8761442
433 + 8761009 = 8761442

Showing the first eight; more decompositions exist.
