Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103972, here are decompositions:

3 + 103969 = 103972
5 + 103967 = 103972
53 + 103919 = 103972
59 + 103913 = 103972
83 + 103889 = 103972
131 + 103841 = 103972
269 + 103703 = 103972
353 + 103619 = 103972

Showing the first eight; more decompositions exist.
