Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599654, here are decompositions:

5 + 31599649 = 31599654
43 + 31599611 = 31599654
101 + 31599553 = 31599654
103 + 31599551 = 31599654
167 + 31599487 = 31599654
223 + 31599431 = 31599654
313 + 31599341 = 31599654
347 + 31599307 = 31599654

Showing the first eight; more decompositions exist.
