Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507852, here are decompositions:

29 + 31507823 = 31507852
59 + 31507793 = 31507852
113 + 31507739 = 31507852
149 + 31507703 = 31507852
191 + 31507661 = 31507852
269 + 31507583 = 31507852
281 + 31507571 = 31507852
449 + 31507403 = 31507852

Showing the first eight; more decompositions exist.
