Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523834, here are decompositions:

31 + 31523803 = 31523834
73 + 31523761 = 31523834
127 + 31523707 = 31523834
313 + 31523521 = 31523834
367 + 31523467 = 31523834
373 + 31523461 = 31523834
487 + 31523347 = 31523834
541 + 31523293 = 31523834

Showing the first eight; more decompositions exist.
