Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452604, here are decompositions:

5 + 31452599 = 31452604
17 + 31452587 = 31452604
83 + 31452521 = 31452604
107 + 31452497 = 31452604
263 + 31452341 = 31452604
401 + 31452203 = 31452604
431 + 31452173 = 31452604
467 + 31452137 = 31452604

Showing the first eight; more decompositions exist.
