Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535372, here are decompositions:

31 + 31535341 = 31535372
61 + 31535311 = 31535372
109 + 31535263 = 31535372
139 + 31535233 = 31535372
199 + 31535173 = 31535372
229 + 31535143 = 31535372
241 + 31535131 = 31535372
313 + 31535059 = 31535372

Showing the first eight; more decompositions exist.
