Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453528, here are decompositions:

5 + 31453523 = 31453528
101 + 31453427 = 31453528
107 + 31453421 = 31453528
137 + 31453391 = 31453528
167 + 31453361 = 31453528
347 + 31453181 = 31453528
677 + 31452851 = 31453528
797 + 31452731 = 31453528

Showing the first eight; more decompositions exist.
