Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452594, here are decompositions:

7 + 31452587 = 31452594
11 + 31452583 = 31452594
23 + 31452571 = 31452594
67 + 31452527 = 31452594
73 + 31452521 = 31452594
97 + 31452497 = 31452594
101 + 31452493 = 31452594
113 + 31452481 = 31452594

Showing the first eight; more decompositions exist.
