Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541694, here are decompositions:

17 + 31541677 = 31541694
43 + 31541651 = 31541694
61 + 31541633 = 31541694
83 + 31541611 = 31541694
97 + 31541597 = 31541694
103 + 31541591 = 31541694
113 + 31541581 = 31541694
131 + 31541563 = 31541694

Showing the first eight; more decompositions exist.
