Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449004, here are decompositions:

17 + 31448987 = 31449004
101 + 31448903 = 31449004
107 + 31448897 = 31449004
113 + 31448891 = 31449004
263 + 31448741 = 31449004
311 + 31448693 = 31449004
383 + 31448621 = 31449004
401 + 31448603 = 31449004

Showing the first eight; more decompositions exist.
