Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20848, here are decompositions:

41 + 20807 = 20848
59 + 20789 = 20848
89 + 20759 = 20848
101 + 20747 = 20848
131 + 20717 = 20848
167 + 20681 = 20848
449 + 20399 = 20848
479 + 20369 = 20848

Showing the first eight; more decompositions exist.
