Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598648, here are decompositions:

127 + 31598521 = 31598648
199 + 31598449 = 31598648
229 + 31598419 = 31598648
271 + 31598377 = 31598648
349 + 31598299 = 31598648
409 + 31598239 = 31598648
421 + 31598227 = 31598648
457 + 31598191 = 31598648

Showing the first eight; more decompositions exist.
