Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590300, here are decompositions:

23 + 31590277 = 31590300
31 + 31590269 = 31590300
37 + 31590263 = 31590300
59 + 31590241 = 31590300
89 + 31590211 = 31590300
113 + 31590187 = 31590300
139 + 31590161 = 31590300
151 + 31590149 = 31590300

Showing the first eight; more decompositions exist.
