Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501132, here are decompositions:

41 + 31501091 = 31501132
71 + 31501061 = 31501132
191 + 31500941 = 31501132
233 + 31500899 = 31501132
269 + 31500863 = 31501132
359 + 31500773 = 31501132
419 + 31500713 = 31501132
431 + 31500701 = 31501132

Showing the first eight; more decompositions exist.
