Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554204, here are decompositions:

5 + 31554199 = 31554204
23 + 31554181 = 31554204
41 + 31554163 = 31554204
43 + 31554161 = 31554204
61 + 31554143 = 31554204
83 + 31554121 = 31554204
127 + 31554077 = 31554204
131 + 31554073 = 31554204

Showing the first eight; more decompositions exist.
