Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532308, here are decompositions:

29 + 31532279 = 31532308
47 + 31532261 = 31532308
89 + 31532219 = 31532308
167 + 31532141 = 31532308
191 + 31532117 = 31532308
491 + 31531817 = 31532308
557 + 31531751 = 31532308
641 + 31531667 = 31532308

Showing the first eight; more decompositions exist.
