Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747662, here are decompositions:

59 + 8747603 = 8747662
83 + 8747579 = 8747662
89 + 8747573 = 8747662
101 + 8747561 = 8747662
149 + 8747513 = 8747662
173 + 8747489 = 8747662
179 + 8747483 = 8747662
191 + 8747471 = 8747662

Showing the first eight; more decompositions exist.
