Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627254, here are decompositions:

5 + 31627249 = 31627254
7 + 31627247 = 31627254
11 + 31627243 = 31627254
17 + 31627237 = 31627254
37 + 31627217 = 31627254
53 + 31627201 = 31627254
103 + 31627151 = 31627254
163 + 31627091 = 31627254

Showing the first eight; more decompositions exist.
