Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601754, here are decompositions:

11 + 31601743 = 31601754
31 + 31601723 = 31601754
43 + 31601711 = 31601754
47 + 31601707 = 31601754
83 + 31601671 = 31601754
103 + 31601651 = 31601754
227 + 31601527 = 31601754
241 + 31601513 = 31601754

Showing the first eight; more decompositions exist.
