Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109740, here are decompositions:

19 + 109721 = 109740
23 + 109717 = 109740
67 + 109673 = 109740
79 + 109661 = 109740
101 + 109639 = 109740
131 + 109609 = 109740
151 + 109589 = 109740
157 + 109583 = 109740

Showing the first eight; more decompositions exist.
