Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618648, here are decompositions:

67 + 8618581 = 8618648
271 + 8618377 = 8618648
331 + 8618317 = 8618648
397 + 8618251 = 8618648
499 + 8618149 = 8618648
541 + 8618107 = 8618648
601 + 8618047 = 8618648
607 + 8618041 = 8618648

Showing the first eight; more decompositions exist.
