Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501462, here are decompositions:

29 + 31501433 = 31501462
53 + 31501409 = 31501462
59 + 31501403 = 31501462
101 + 31501361 = 31501462
131 + 31501331 = 31501462
149 + 31501313 = 31501462
233 + 31501229 = 31501462
263 + 31501199 = 31501462

Showing the first eight; more decompositions exist.
