Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738680, here are decompositions:

89 + 8738591 = 8738680
101 + 8738579 = 8738680
113 + 8738567 = 8738680
173 + 8738507 = 8738680
233 + 8738447 = 8738680
281 + 8738399 = 8738680
317 + 8738363 = 8738680
347 + 8738333 = 8738680

Showing the first eight; more decompositions exist.
