Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501348, here are decompositions:

17 + 31501331 = 31501348
101 + 31501247 = 31501348
149 + 31501199 = 31501348
257 + 31501091 = 31501348
311 + 31501037 = 31501348
401 + 31500947 = 31501348
449 + 31500899 = 31501348
647 + 31500701 = 31501348

Showing the first eight; more decompositions exist.
