Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598544, here are decompositions:

7 + 31598537 = 31598544
23 + 31598521 = 31598544
31 + 31598513 = 31598544
127 + 31598417 = 31598544
163 + 31598381 = 31598544
167 + 31598377 = 31598544
181 + 31598363 = 31598544
191 + 31598353 = 31598544

Showing the first eight; more decompositions exist.
