Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104072, here are decompositions:

13 + 104059 = 104072
19 + 104053 = 104072
79 + 103993 = 104072
103 + 103969 = 104072
109 + 103963 = 104072
229 + 103843 = 104072
271 + 103801 = 104072
349 + 103723 = 104072

Showing the first eight; more decompositions exist.
