Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472634, here are decompositions:

23 + 31472611 = 31472634
43 + 31472591 = 31472634
47 + 31472587 = 31472634
97 + 31472537 = 31472634
197 + 31472437 = 31472634
283 + 31472351 = 31472634
373 + 31472261 = 31472634
433 + 31472201 = 31472634

Showing the first eight; more decompositions exist.
