Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601744, here are decompositions:

37 + 31601707 = 31601744
73 + 31601671 = 31601744
193 + 31601551 = 31601744
271 + 31601473 = 31601744
337 + 31601407 = 31601744
397 + 31601347 = 31601744
541 + 31601203 = 31601744
607 + 31601137 = 31601744

Showing the first eight; more decompositions exist.
