Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505744, here are decompositions:

3 + 31505741 = 31505744
7 + 31505737 = 31505744
13 + 31505731 = 31505744
43 + 31505701 = 31505744
211 + 31505533 = 31505744
223 + 31505521 = 31505744
271 + 31505473 = 31505744
313 + 31505431 = 31505744

Showing the first eight; more decompositions exist.
