Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475452, here are decompositions:

23 + 31475429 = 31475452
59 + 31475393 = 31475452
131 + 31475321 = 31475452
263 + 31475189 = 31475452
293 + 31475159 = 31475452
311 + 31475141 = 31475452
353 + 31475099 = 31475452
383 + 31475069 = 31475452

Showing the first eight; more decompositions exist.
