Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472624, here are decompositions:

13 + 31472611 = 31472624
37 + 31472587 = 31472624
331 + 31472293 = 31472624
433 + 31472191 = 31472624
457 + 31472167 = 31472624
571 + 31472053 = 31472624
613 + 31472011 = 31472624
691 + 31471933 = 31472624

Showing the first eight; more decompositions exist.
