Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501412, here are decompositions:

3 + 31501409 = 31501412
13 + 31501399 = 31501412
79 + 31501333 = 31501412
109 + 31501303 = 31501412
181 + 31501231 = 31501412
193 + 31501219 = 31501412
211 + 31501201 = 31501412
331 + 31501081 = 31501412

Showing the first eight; more decompositions exist.
