Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494524, here are decompositions:

97 + 31494427 = 31494524
223 + 31494301 = 31494524
277 + 31494247 = 31494524
283 + 31494241 = 31494524
367 + 31494157 = 31494524
433 + 31494091 = 31494524
541 + 31493983 = 31494524
643 + 31493881 = 31494524

Showing the first eight; more decompositions exist.
