Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554300, here are decompositions:

13 + 31554287 = 31554300
17 + 31554283 = 31554300
59 + 31554241 = 31554300
101 + 31554199 = 31554300
137 + 31554163 = 31554300
139 + 31554161 = 31554300
157 + 31554143 = 31554300
179 + 31554121 = 31554300

Showing the first eight; more decompositions exist.
