Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609452, here are decompositions:

59 + 31609393 = 31609452
71 + 31609381 = 31609452
113 + 31609339 = 31609452
163 + 31609289 = 31609452
223 + 31609229 = 31609452
229 + 31609223 = 31609452
239 + 31609213 = 31609452
263 + 31609189 = 31609452

Showing the first eight; more decompositions exist.
