Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532348, here are decompositions:

7 + 31532341 = 31532348
19 + 31532329 = 31532348
79 + 31532269 = 31532348
139 + 31532209 = 31532348
181 + 31532167 = 31532348
277 + 31532071 = 31532348
439 + 31531909 = 31532348
709 + 31531639 = 31532348

Showing the first eight; more decompositions exist.
