Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598764, here are decompositions:

11 + 31598753 = 31598764
47 + 31598717 = 31598764
173 + 31598591 = 31598764
227 + 31598537 = 31598764
251 + 31598513 = 31598764
347 + 31598417 = 31598764
383 + 31598381 = 31598764
401 + 31598363 = 31598764

Showing the first eight; more decompositions exist.
