Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528132, here are decompositions:

5 + 31528127 = 31528132
11 + 31528121 = 31528132
29 + 31528103 = 31528132
113 + 31528019 = 31528132
131 + 31528001 = 31528132
191 + 31527941 = 31528132
431 + 31527701 = 31528132
443 + 31527689 = 31528132

Showing the first eight; more decompositions exist.
