Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541754, here are decompositions:

17 + 31541737 = 31541754
47 + 31541707 = 31541754
61 + 31541693 = 31541754
103 + 31541651 = 31541754
157 + 31541597 = 31541754
163 + 31541591 = 31541754
173 + 31541581 = 31541754
191 + 31541563 = 31541754

Showing the first eight; more decompositions exist.
