Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618726, here are decompositions:

37 + 8618689 = 8618726
43 + 8618683 = 8618726
283 + 8618443 = 8618726
313 + 8618413 = 8618726
349 + 8618377 = 8618726
397 + 8618329 = 8618726
409 + 8618317 = 8618726
433 + 8618293 = 8618726

Showing the first eight; more decompositions exist.
