Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598502, here are decompositions:

43 + 31598459 = 31598502
53 + 31598449 = 31598502
79 + 31598423 = 31598502
83 + 31598419 = 31598502
101 + 31598401 = 31598502
139 + 31598363 = 31598502
149 + 31598353 = 31598502
181 + 31598321 = 31598502

Showing the first eight; more decompositions exist.
