Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455604, here are decompositions:

71 + 31455533 = 31455604
83 + 31455521 = 31455604
101 + 31455503 = 31455604
233 + 31455371 = 31455604
311 + 31455293 = 31455604
443 + 31455161 = 31455604
563 + 31455041 = 31455604
647 + 31454957 = 31455604

Showing the first eight; more decompositions exist.
