Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590774, here are decompositions:

11 + 31590763 = 31590774
37 + 31590737 = 31590774
41 + 31590733 = 31590774
43 + 31590731 = 31590774
107 + 31590667 = 31590774
157 + 31590617 = 31590774
181 + 31590593 = 31590774
191 + 31590583 = 31590774

Showing the first eight; more decompositions exist.
