Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452374, here are decompositions:

7 + 31452367 = 31452374
73 + 31452301 = 31452374
193 + 31452181 = 31452374
277 + 31452097 = 31452374
313 + 31452061 = 31452374
367 + 31452007 = 31452374
643 + 31451731 = 31452374
661 + 31451713 = 31452374

Showing the first eight; more decompositions exist.
