Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554174, here are decompositions:

11 + 31554163 = 31554174
13 + 31554161 = 31554174
31 + 31554143 = 31554174
53 + 31554121 = 31554174
97 + 31554077 = 31554174
101 + 31554073 = 31554174
131 + 31554043 = 31554174
163 + 31554011 = 31554174

Showing the first eight; more decompositions exist.
