Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598572, here are decompositions:

29 + 31598543 = 31598572
53 + 31598519 = 31598572
59 + 31598513 = 31598572
113 + 31598459 = 31598572
149 + 31598423 = 31598572
191 + 31598381 = 31598572
251 + 31598321 = 31598572
293 + 31598279 = 31598572

Showing the first eight; more decompositions exist.
