Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532692, here are decompositions:

5 + 31532687 = 31532692
53 + 31532639 = 31532692
263 + 31532429 = 31532692
353 + 31532339 = 31532692
431 + 31532261 = 31532692
761 + 31531931 = 31532692
809 + 31531883 = 31532692
941 + 31531751 = 31532692

Showing the first eight; more decompositions exist.
