Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598558, here are decompositions:

37 + 31598521 = 31598558
109 + 31598449 = 31598558
139 + 31598419 = 31598558
157 + 31598401 = 31598558
181 + 31598377 = 31598558
331 + 31598227 = 31598558
367 + 31598191 = 31598558
379 + 31598179 = 31598558

Showing the first eight; more decompositions exist.
