Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452008, here are decompositions:

79 + 31451929 = 31452008
127 + 31451881 = 31452008
139 + 31451869 = 31452008
151 + 31451857 = 31452008
277 + 31451731 = 31452008
421 + 31451587 = 31452008
487 + 31451521 = 31452008
547 + 31451461 = 31452008

Showing the first eight; more decompositions exist.
