Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452172, here are decompositions:

41 + 31452131 = 31452172
83 + 31452089 = 31452172
131 + 31452041 = 31452172
173 + 31451999 = 31452172
179 + 31451993 = 31452172
263 + 31451909 = 31452172
419 + 31451753 = 31452172
443 + 31451729 = 31452172

Showing the first eight; more decompositions exist.
