Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598436, here are decompositions:

13 + 31598423 = 31598436
17 + 31598419 = 31598436
19 + 31598417 = 31598436
59 + 31598377 = 31598436
73 + 31598363 = 31598436
83 + 31598353 = 31598436
109 + 31598327 = 31598436
137 + 31598299 = 31598436

Showing the first eight; more decompositions exist.
