Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541432, here are decompositions:

3 + 31541429 = 31541432
31 + 31541401 = 31541432
73 + 31541359 = 31541432
151 + 31541281 = 31541432
163 + 31541269 = 31541432
199 + 31541233 = 31541432
271 + 31541161 = 31541432
331 + 31541101 = 31541432

Showing the first eight; more decompositions exist.
