Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535384, here are decompositions:

3 + 31535381 = 31535384
7 + 31535377 = 31535384
43 + 31535341 = 31535384
73 + 31535311 = 31535384
151 + 31535233 = 31535384
157 + 31535227 = 31535384
211 + 31535173 = 31535384
241 + 31535143 = 31535384

Showing the first eight; more decompositions exist.
