Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637434, here are decompositions:

7 + 8637427 = 8637434
61 + 8637373 = 8637434
97 + 8637337 = 8637434
181 + 8637253 = 8637434
271 + 8637163 = 8637434
283 + 8637151 = 8637434
331 + 8637103 = 8637434
367 + 8637067 = 8637434

Showing the first eight; more decompositions exist.
