Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452112, here are decompositions:

23 + 31452089 = 31452112
71 + 31452041 = 31452112
113 + 31451999 = 31452112
311 + 31451801 = 31452112
359 + 31451753 = 31452112
383 + 31451729 = 31452112
389 + 31451723 = 31452112
401 + 31451711 = 31452112

Showing the first eight; more decompositions exist.
