Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598624, here are decompositions:

103 + 31598521 = 31598624
223 + 31598401 = 31598624
271 + 31598353 = 31598624
397 + 31598227 = 31598624
433 + 31598191 = 31598624
487 + 31598137 = 31598624
523 + 31598101 = 31598624
613 + 31598011 = 31598624

Showing the first eight; more decompositions exist.
