Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517374, here are decompositions:

101 + 31517273 = 31517374
107 + 31517267 = 31517374
131 + 31517243 = 31517374
167 + 31517207 = 31517374
311 + 31517063 = 31517374
347 + 31517027 = 31517374
353 + 31517021 = 31517374
401 + 31516973 = 31517374

Showing the first eight; more decompositions exist.
