Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472754, here are decompositions:

31 + 31472723 = 31472754
163 + 31472591 = 31472754
167 + 31472587 = 31472754
317 + 31472437 = 31472754
461 + 31472293 = 31472754
463 + 31472291 = 31472754
563 + 31472191 = 31472754
571 + 31472183 = 31472754

Showing the first eight; more decompositions exist.
