Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598616, here are decompositions:

73 + 31598543 = 31598616
79 + 31598537 = 31598616
97 + 31598519 = 31598616
103 + 31598513 = 31598616
157 + 31598459 = 31598616
167 + 31598449 = 31598616
193 + 31598423 = 31598616
197 + 31598419 = 31598616

Showing the first eight; more decompositions exist.
