Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109972, here are decompositions:

11 + 109961 = 109972
29 + 109943 = 109972
53 + 109919 = 109972
59 + 109913 = 109972
89 + 109883 = 109972
113 + 109859 = 109972
131 + 109841 = 109972
179 + 109793 = 109972

Showing the first eight; more decompositions exist.
