Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534372, here are decompositions:

3 + 31534369 = 31534372
29 + 31534343 = 31534372
71 + 31534301 = 31534372
101 + 31534271 = 31534372
131 + 31534241 = 31534372
173 + 31534199 = 31534372
251 + 31534121 = 31534372
269 + 31534103 = 31534372

Showing the first eight; more decompositions exist.
