Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621434, here are decompositions:

5 + 8621429 = 8621434
23 + 8621411 = 8621434
191 + 8621243 = 8621434
197 + 8621237 = 8621434
233 + 8621201 = 8621434
251 + 8621183 = 8621434
281 + 8621153 = 8621434
347 + 8621087 = 8621434

Showing the first eight; more decompositions exist.
