Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448014, here are decompositions:

47 + 31447967 = 31448014
53 + 31447961 = 31448014
83 + 31447931 = 31448014
113 + 31447901 = 31448014
263 + 31447751 = 31448014
347 + 31447667 = 31448014
383 + 31447631 = 31448014
431 + 31447583 = 31448014

Showing the first eight; more decompositions exist.
