Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543906, here are decompositions:

3 + 31543903 = 31543906
29 + 31543877 = 31543906
47 + 31543859 = 31543906
59 + 31543847 = 31543906
89 + 31543817 = 31543906
137 + 31543769 = 31543906
263 + 31543643 = 31543906
509 + 31543397 = 31543906

Showing the first eight; more decompositions exist.
