Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972154, here are decompositions:

17 + 972137 = 972154
23 + 972131 = 972154
41 + 972113 = 972154
83 + 972071 = 972154
107 + 972047 = 972154
137 + 972017 = 972154
173 + 971981 = 972154
233 + 971921 = 972154

Showing the first eight; more decompositions exist.
