Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598642, here are decompositions:

193 + 31598449 = 31598642
223 + 31598419 = 31598642
241 + 31598401 = 31598642
463 + 31598179 = 31598642
499 + 31598143 = 31598642
541 + 31598101 = 31598642
613 + 31598029 = 31598642
631 + 31598011 = 31598642

Showing the first eight; more decompositions exist.
