Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453450, here are decompositions:

3 + 31453447 = 31453450
23 + 31453427 = 31453450
29 + 31453421 = 31453450
59 + 31453391 = 31453450
89 + 31453361 = 31453450
167 + 31453283 = 31453450
257 + 31453193 = 31453450
269 + 31453181 = 31453450

Showing the first eight; more decompositions exist.
