Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467372, here are decompositions:

5 + 31467367 = 31467372
43 + 31467329 = 31467372
61 + 31467311 = 31467372
71 + 31467301 = 31467372
113 + 31467259 = 31467372
173 + 31467199 = 31467372
191 + 31467181 = 31467372
239 + 31467133 = 31467372

Showing the first eight; more decompositions exist.
