Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488300, here are decompositions:

7 + 31488293 = 31488300
29 + 31488271 = 31488300
43 + 31488257 = 31488300
73 + 31488227 = 31488300
89 + 31488211 = 31488300
97 + 31488203 = 31488300
139 + 31488161 = 31488300
163 + 31488137 = 31488300

Showing the first eight; more decompositions exist.
