Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448436, here are decompositions:

13 + 31448423 = 31448436
23 + 31448413 = 31448436
59 + 31448377 = 31448436
67 + 31448369 = 31448436
113 + 31448323 = 31448436
127 + 31448309 = 31448436
137 + 31448299 = 31448436
139 + 31448297 = 31448436

Showing the first eight; more decompositions exist.
