Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627394, here are decompositions:

3 + 31627391 = 31627394
37 + 31627357 = 31627394
61 + 31627333 = 31627394
151 + 31627243 = 31627394
157 + 31627237 = 31627394
193 + 31627201 = 31627394
367 + 31627027 = 31627394
607 + 31626787 = 31627394

Showing the first eight; more decompositions exist.
