Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452272, here are decompositions:

31 + 31452241 = 31452272
73 + 31452199 = 31452272
151 + 31452121 = 31452272
193 + 31452079 = 31452272
211 + 31452061 = 31452272
433 + 31451839 = 31452272
541 + 31451731 = 31452272
751 + 31451521 = 31452272

Showing the first eight; more decompositions exist.
