Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449014, here are decompositions:

151 + 31448863 = 31449014
193 + 31448821 = 31449014
211 + 31448803 = 31449014
307 + 31448707 = 31449014
367 + 31448647 = 31449014
433 + 31448581 = 31449014
463 + 31448551 = 31449014
601 + 31448413 = 31449014

Showing the first eight; more decompositions exist.
