Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634142, here are decompositions:

3 + 8634139 = 8634142
5 + 8634137 = 8634142
89 + 8634053 = 8634142
191 + 8633951 = 8634142
281 + 8633861 = 8634142
431 + 8633711 = 8634142
443 + 8633699 = 8634142
479 + 8633663 = 8634142

Showing the first eight; more decompositions exist.
