Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598974, here are decompositions:

41 + 31598933 = 31598974
47 + 31598927 = 31598974
101 + 31598873 = 31598974
107 + 31598867 = 31598974
191 + 31598783 = 31598974
257 + 31598717 = 31598974
383 + 31598591 = 31598974
431 + 31598543 = 31598974

Showing the first eight; more decompositions exist.
