Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11898, here are decompositions:

11 + 11887 = 11898
31 + 11867 = 11898
59 + 11839 = 11898
67 + 11831 = 11898
71 + 11827 = 11898
97 + 11801 = 11898
109 + 11789 = 11898
167 + 11731 = 11898

Showing the first eight; more decompositions exist.
