Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620562, here are decompositions:

19 + 8620543 = 8620562
193 + 8620369 = 8620562
331 + 8620231 = 8620562
373 + 8620189 = 8620562
421 + 8620141 = 8620562
499 + 8620063 = 8620562
619 + 8619943 = 8620562
751 + 8619811 = 8620562

Showing the first eight; more decompositions exist.
