Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598512, here are decompositions:

53 + 31598459 = 31598512
89 + 31598423 = 31598512
131 + 31598381 = 31598512
149 + 31598363 = 31598512
191 + 31598321 = 31598512
233 + 31598279 = 31598512
251 + 31598261 = 31598512
311 + 31598201 = 31598512

Showing the first eight; more decompositions exist.
