Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101898, here are decompositions:

7 + 101891 = 101898
19 + 101879 = 101898
29 + 101869 = 101898
59 + 101839 = 101898
61 + 101837 = 101898
101 + 101797 = 101898
109 + 101789 = 101898
127 + 101771 = 101898

Showing the first eight; more decompositions exist.
