Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452254, here are decompositions:

13 + 31452241 = 31452254
73 + 31452181 = 31452254
157 + 31452097 = 31452254
193 + 31452061 = 31452254
241 + 31452013 = 31452254
373 + 31451881 = 31452254
397 + 31451857 = 31452254
523 + 31451731 = 31452254

Showing the first eight; more decompositions exist.
