Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472734, here are decompositions:

11 + 31472723 = 31472734
71 + 31472663 = 31472734
101 + 31472633 = 31472734
197 + 31472537 = 31472734
233 + 31472501 = 31472734
383 + 31472351 = 31472734
443 + 31472291 = 31472734
743 + 31471991 = 31472734

Showing the first eight; more decompositions exist.
