Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627252, here are decompositions:

3 + 31627249 = 31627252
5 + 31627247 = 31627252
101 + 31627151 = 31627252
131 + 31627121 = 31627252
179 + 31627073 = 31627252
353 + 31626899 = 31627252
359 + 31626893 = 31627252
383 + 31626869 = 31627252

Showing the first eight; more decompositions exist.
