Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649236, here are decompositions:

157 + 8649079 = 8649236
283 + 8648953 = 8649236
307 + 8648929 = 8649236
313 + 8648923 = 8649236
373 + 8648863 = 8649236
397 + 8648839 = 8649236
439 + 8648797 = 8649236
457 + 8648779 = 8649236

Showing the first eight; more decompositions exist.
