Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454932, here are decompositions:

23 + 31454909 = 31454932
29 + 31454903 = 31454932
59 + 31454873 = 31454932
149 + 31454783 = 31454932
191 + 31454741 = 31454932
251 + 31454681 = 31454932
263 + 31454669 = 31454932
281 + 31454651 = 31454932

Showing the first eight; more decompositions exist.
