Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101928, here are decompositions:

7 + 101921 = 101928
11 + 101917 = 101928
37 + 101891 = 101928
59 + 101869 = 101928
89 + 101839 = 101928
131 + 101797 = 101928
139 + 101789 = 101928
157 + 101771 = 101928

Showing the first eight; more decompositions exist.
