Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627346, here are decompositions:

13 + 31627333 = 31627346
43 + 31627303 = 31627346
97 + 31627249 = 31627346
103 + 31627243 = 31627346
109 + 31627237 = 31627346
277 + 31627069 = 31627346
313 + 31627033 = 31627346
367 + 31626979 = 31627346

Showing the first eight; more decompositions exist.
