Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599460, here are decompositions:

29 + 31599431 = 31599460
71 + 31599389 = 31599460
107 + 31599353 = 31599460
359 + 31599101 = 31599460
401 + 31599059 = 31599460
521 + 31598939 = 31599460
587 + 31598873 = 31599460
593 + 31598867 = 31599460

Showing the first eight; more decompositions exist.
