Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452422, here are decompositions:

3 + 31452419 = 31452422
139 + 31452283 = 31452422
181 + 31452241 = 31452422
223 + 31452199 = 31452422
241 + 31452181 = 31452422
409 + 31452013 = 31452422
541 + 31451881 = 31452422
691 + 31451731 = 31452422

Showing the first eight; more decompositions exist.
