Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532174, here are decompositions:

7 + 31532167 = 31532174
61 + 31532113 = 31532174
103 + 31532071 = 31532174
547 + 31531627 = 31532174
691 + 31531483 = 31532174
757 + 31531417 = 31532174
907 + 31531267 = 31532174
1117 + 31531057 = 31532174

Showing the first eight; more decompositions exist.
