Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494592, here are decompositions:

11 + 31494581 = 31494592
83 + 31494509 = 31494592
89 + 31494503 = 31494592
113 + 31494479 = 31494592
149 + 31494443 = 31494592
191 + 31494401 = 31494592
431 + 31494161 = 31494592
449 + 31494143 = 31494592

Showing the first eight; more decompositions exist.
