Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598684, here are decompositions:

37 + 31598647 = 31598684
163 + 31598521 = 31598684
283 + 31598401 = 31598684
307 + 31598377 = 31598684
331 + 31598353 = 31598684
457 + 31598227 = 31598684
541 + 31598143 = 31598684
547 + 31598137 = 31598684

Showing the first eight; more decompositions exist.
