Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554272, here are decompositions:

31 + 31554241 = 31554272
73 + 31554199 = 31554272
109 + 31554163 = 31554272
151 + 31554121 = 31554272
199 + 31554073 = 31554272
229 + 31554043 = 31554272
439 + 31553833 = 31554272
601 + 31553671 = 31554272

Showing the first eight; more decompositions exist.
