Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532452, here are decompositions:

23 + 31532429 = 31532452
113 + 31532339 = 31532452
173 + 31532279 = 31532452
191 + 31532261 = 31532452
233 + 31532219 = 31532452
311 + 31532141 = 31532452
389 + 31532063 = 31532452
431 + 31532021 = 31532452

Showing the first eight; more decompositions exist.
