Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543854, here are decompositions:

7 + 31543847 = 31543854
11 + 31543843 = 31543854
37 + 31543817 = 31543854
71 + 31543783 = 31543854
103 + 31543751 = 31543854
131 + 31543723 = 31543854
157 + 31543697 = 31543854
163 + 31543691 = 31543854

Showing the first eight; more decompositions exist.
