Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559754, here are decompositions:

67 + 31559687 = 31559754
73 + 31559681 = 31559754
101 + 31559653 = 31559754
103 + 31559651 = 31559754
113 + 31559641 = 31559754
131 + 31559623 = 31559754
181 + 31559573 = 31559754
283 + 31559471 = 31559754

Showing the first eight; more decompositions exist.
