Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452088, here are decompositions:

47 + 31452041 = 31452088
89 + 31451999 = 31452088
179 + 31451909 = 31452088
251 + 31451837 = 31452088
281 + 31451807 = 31452088
359 + 31451729 = 31452088
389 + 31451699 = 31452088
431 + 31451657 = 31452088

Showing the first eight; more decompositions exist.
