Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627442, here are decompositions:

11 + 8627431 = 8627442
13 + 8627429 = 8627442
71 + 8627371 = 8627442
79 + 8627363 = 8627442
101 + 8627341 = 8627442
113 + 8627329 = 8627442
191 + 8627251 = 8627442
199 + 8627243 = 8627442

Showing the first eight; more decompositions exist.
