Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517346, here are decompositions:

73 + 31517273 = 31517346
79 + 31517267 = 31517346
103 + 31517243 = 31517346
139 + 31517207 = 31517346
149 + 31517197 = 31517346
197 + 31517149 = 31517346
283 + 31517063 = 31517346
307 + 31517039 = 31517346

Showing the first eight; more decompositions exist.
