Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72100, here are decompositions:

11 + 72089 = 72100
23 + 72077 = 72100
47 + 72053 = 72100
53 + 72047 = 72100
101 + 71999 = 72100
107 + 71993 = 72100
113 + 71987 = 72100
137 + 71963 = 72100

Showing the first eight; more decompositions exist.
