Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517352, here are decompositions:

79 + 31517273 = 31517352
109 + 31517243 = 31517352
313 + 31517039 = 31517352
331 + 31517021 = 31517352
359 + 31516993 = 31517352
379 + 31516973 = 31517352
401 + 31516951 = 31517352
463 + 31516889 = 31517352

Showing the first eight; more decompositions exist.
