Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501452, here are decompositions:

5 + 31501447 = 31501452
19 + 31501433 = 31501452
43 + 31501409 = 31501452
53 + 31501399 = 31501452
131 + 31501321 = 31501452
139 + 31501313 = 31501452
149 + 31501303 = 31501452
223 + 31501229 = 31501452

Showing the first eight; more decompositions exist.
