Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543742, here are decompositions:

19 + 31543723 = 31543742
31 + 31543711 = 31543742
73 + 31543669 = 31543742
163 + 31543579 = 31543742
199 + 31543543 = 31543742
211 + 31543531 = 31543742
313 + 31543429 = 31543742
499 + 31543243 = 31543742

Showing the first eight; more decompositions exist.
