Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448552, here are decompositions:

19 + 31448533 = 31448552
73 + 31448479 = 31448552
103 + 31448449 = 31448552
139 + 31448413 = 31448552
229 + 31448323 = 31448552
271 + 31448281 = 31448552
601 + 31447951 = 31448552
739 + 31447813 = 31448552

Showing the first eight; more decompositions exist.
