Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720762, here are decompositions:

73 + 8720689 = 8720762
139 + 8720623 = 8720762
181 + 8720581 = 8720762
229 + 8720533 = 8720762
283 + 8720479 = 8720762
331 + 8720431 = 8720762
373 + 8720389 = 8720762
571 + 8720191 = 8720762

Showing the first eight; more decompositions exist.
