Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532248, here are decompositions:

29 + 31532219 = 31532248
107 + 31532141 = 31532248
131 + 31532117 = 31532248
227 + 31532021 = 31532248
281 + 31531967 = 31532248
317 + 31531931 = 31532248
431 + 31531817 = 31532248
521 + 31531727 = 31532248

Showing the first eight; more decompositions exist.
