Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452004, here are decompositions:

5 + 31451999 = 31452004
11 + 31451993 = 31452004
167 + 31451837 = 31452004
197 + 31451807 = 31452004
251 + 31451753 = 31452004
281 + 31451723 = 31452004
293 + 31451711 = 31452004
347 + 31451657 = 31452004

Showing the first eight; more decompositions exist.
