Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498372, here are decompositions:

5 + 31498367 = 31498372
23 + 31498349 = 31498372
29 + 31498343 = 31498372
83 + 31498289 = 31498372
173 + 31498199 = 31498372
179 + 31498193 = 31498372
431 + 31497941 = 31498372
443 + 31497929 = 31498372

Showing the first eight; more decompositions exist.
