Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448032, here are decompositions:

71 + 31447961 = 31448032
101 + 31447931 = 31448032
131 + 31447901 = 31448032
179 + 31447853 = 31448032
233 + 31447799 = 31448032
263 + 31447769 = 31448032
281 + 31447751 = 31448032
359 + 31447673 = 31448032

Showing the first eight; more decompositions exist.
