Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464532, here are decompositions:

23 + 31464509 = 31464532
89 + 31464443 = 31464532
131 + 31464401 = 31464532
173 + 31464359 = 31464532
191 + 31464341 = 31464532
251 + 31464281 = 31464532
263 + 31464269 = 31464532
383 + 31464149 = 31464532

Showing the first eight; more decompositions exist.
