Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598842, here are decompositions:

3 + 31598839 = 31598842
53 + 31598789 = 31598842
59 + 31598783 = 31598842
71 + 31598771 = 31598842
89 + 31598753 = 31598842
173 + 31598669 = 31598842
251 + 31598591 = 31598842
383 + 31598459 = 31598842

Showing the first eight; more decompositions exist.
