Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544352, here are decompositions:

5 + 31544347 = 31544352
29 + 31544323 = 31544352
41 + 31544311 = 31544352
71 + 31544281 = 31544352
131 + 31544221 = 31544352
139 + 31544213 = 31544352
163 + 31544189 = 31544352
173 + 31544179 = 31544352

Showing the first eight; more decompositions exist.
