Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543244, here are decompositions:

13 + 31543231 = 31543244
37 + 31543207 = 31543244
277 + 31542967 = 31543244
307 + 31542937 = 31543244
367 + 31542877 = 31543244
433 + 31542811 = 31543244
457 + 31542787 = 31543244
541 + 31542703 = 31543244

Showing the first eight; more decompositions exist.
