Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547430, here are decompositions:

17 + 31547413 = 31547430
73 + 31547357 = 31547430
113 + 31547317 = 31547430
127 + 31547303 = 31547430
149 + 31547281 = 31547430
163 + 31547267 = 31547430
199 + 31547231 = 31547430
227 + 31547203 = 31547430

Showing the first eight; more decompositions exist.
