Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501476, here are decompositions:

29 + 31501447 = 31501476
43 + 31501433 = 31501476
67 + 31501409 = 31501476
73 + 31501403 = 31501476
89 + 31501387 = 31501476
163 + 31501313 = 31501476
173 + 31501303 = 31501476
229 + 31501247 = 31501476

Showing the first eight; more decompositions exist.
