Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452556, here are decompositions:

17 + 31452539 = 31452556
29 + 31452527 = 31452556
59 + 31452497 = 31452556
137 + 31452419 = 31452556
347 + 31452209 = 31452556
353 + 31452203 = 31452556
383 + 31452173 = 31452556
419 + 31452137 = 31452556

Showing the first eight; more decompositions exist.
