Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598492, here are decompositions:

43 + 31598449 = 31598492
73 + 31598419 = 31598492
139 + 31598353 = 31598492
193 + 31598299 = 31598492
313 + 31598179 = 31598492
349 + 31598143 = 31598492
463 + 31598029 = 31598492
613 + 31597879 = 31598492

Showing the first eight; more decompositions exist.
