Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744620, here are decompositions:

83 + 8744537 = 8744620
107 + 8744513 = 8744620
113 + 8744507 = 8744620
173 + 8744447 = 8744620
197 + 8744423 = 8744620
359 + 8744261 = 8744620
431 + 8744189 = 8744620
491 + 8744129 = 8744620

Showing the first eight; more decompositions exist.
