Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489332, here are decompositions:

53 + 31489279 = 31489332
73 + 31489259 = 31489332
89 + 31489243 = 31489332
103 + 31489229 = 31489332
139 + 31489193 = 31489332
151 + 31489181 = 31489332
163 + 31489169 = 31489332
241 + 31489091 = 31489332

Showing the first eight; more decompositions exist.
