Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501294, here are decompositions:

47 + 31501247 = 31501294
233 + 31501061 = 31501294
257 + 31501037 = 31501294
317 + 31500977 = 31501294
347 + 31500947 = 31501294
353 + 31500941 = 31501294
431 + 31500863 = 31501294
521 + 31500773 = 31501294

Showing the first eight; more decompositions exist.
