Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541526, here are decompositions:

17 + 31541509 = 31541526
19 + 31541507 = 31541526
43 + 31541483 = 31541526
59 + 31541467 = 31541526
89 + 31541437 = 31541526
97 + 31541429 = 31541526
109 + 31541417 = 31541526
127 + 31541399 = 31541526

Showing the first eight; more decompositions exist.
