Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452136, here are decompositions:

5 + 31452131 = 31452136
47 + 31452089 = 31452136
137 + 31451999 = 31452136
167 + 31451969 = 31452136
227 + 31451909 = 31452136
383 + 31451753 = 31452136
479 + 31451657 = 31452136
557 + 31451579 = 31452136

Showing the first eight; more decompositions exist.
