Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593904, here are decompositions:

3 + 31593901 = 31593904
71 + 31593833 = 31593904
107 + 31593797 = 31593904
137 + 31593767 = 31593904
257 + 31593647 = 31593904
263 + 31593641 = 31593904
401 + 31593503 = 31593904
443 + 31593461 = 31593904

Showing the first eight; more decompositions exist.
