Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562330, here are decompositions:

31 + 31562299 = 31562330
67 + 31562263 = 31562330
73 + 31562257 = 31562330
193 + 31562137 = 31562330
211 + 31562119 = 31562330
223 + 31562107 = 31562330
277 + 31562053 = 31562330
307 + 31562023 = 31562330

Showing the first eight; more decompositions exist.
