Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526144, here are decompositions:

3 + 31526141 = 31526144
61 + 31526083 = 31526144
163 + 31525981 = 31526144
193 + 31525951 = 31526144
241 + 31525903 = 31526144
367 + 31525777 = 31526144
373 + 31525771 = 31526144
421 + 31525723 = 31526144

Showing the first eight; more decompositions exist.
