Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529350, here are decompositions:

3 + 31529347 = 31529350
29 + 31529321 = 31529350
71 + 31529279 = 31529350
101 + 31529249 = 31529350
107 + 31529243 = 31529350
131 + 31529219 = 31529350
137 + 31529213 = 31529350
263 + 31529087 = 31529350

Showing the first eight; more decompositions exist.
