Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28762, here are decompositions:

3 + 28759 = 28762
11 + 28751 = 28762
59 + 28703 = 28762
101 + 28661 = 28762
113 + 28649 = 28762
131 + 28631 = 28762
191 + 28571 = 28762
263 + 28499 = 28762

Showing the first eight; more decompositions exist.
