Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69800, here are decompositions:

37 + 69763 = 69800
61 + 69739 = 69800
103 + 69697 = 69800
109 + 69691 = 69800
139 + 69661 = 69800
307 + 69493 = 69800
337 + 69463 = 69800
373 + 69427 = 69800

Showing the first eight; more decompositions exist.
