Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495892, here are decompositions:

13 + 31495879 = 31495892
73 + 31495819 = 31495892
139 + 31495753 = 31495892
151 + 31495741 = 31495892
163 + 31495729 = 31495892
199 + 31495693 = 31495892
229 + 31495663 = 31495892
541 + 31495351 = 31495892

Showing the first eight; more decompositions exist.
