Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749226, here are decompositions:

7 + 8749219 = 8749226
19 + 8749207 = 8749226
139 + 8749087 = 8749226
337 + 8748889 = 8749226
349 + 8748877 = 8749226
373 + 8748853 = 8749226
379 + 8748847 = 8749226
439 + 8748787 = 8749226

Showing the first eight; more decompositions exist.
