Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593804, here are decompositions:

7 + 31593797 = 31593804
17 + 31593787 = 31593804
37 + 31593767 = 31593804
41 + 31593763 = 31593804
83 + 31593721 = 31593804
101 + 31593703 = 31593804
157 + 31593647 = 31593804
163 + 31593641 = 31593804

Showing the first eight; more decompositions exist.
