Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623402, here are decompositions:

29 + 31623373 = 31623402
59 + 31623343 = 31623402
179 + 31623223 = 31623402
191 + 31623211 = 31623402
193 + 31623209 = 31623402
229 + 31623173 = 31623402
233 + 31623169 = 31623402
281 + 31623121 = 31623402

Showing the first eight; more decompositions exist.
