Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598612, here are decompositions:

163 + 31598449 = 31598612
193 + 31598419 = 31598612
211 + 31598401 = 31598612
313 + 31598299 = 31598612
373 + 31598239 = 31598612
421 + 31598191 = 31598612
433 + 31598179 = 31598612
601 + 31598011 = 31598612

Showing the first eight; more decompositions exist.
