Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598488, here are decompositions:

29 + 31598459 = 31598488
71 + 31598417 = 31598488
107 + 31598381 = 31598488
167 + 31598321 = 31598488
227 + 31598261 = 31598488
347 + 31598141 = 31598488
431 + 31598057 = 31598488
461 + 31598027 = 31598488

Showing the first eight; more decompositions exist.
