Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472604, here are decompositions:

13 + 31472591 = 31472604
17 + 31472587 = 31472604
67 + 31472537 = 31472604
103 + 31472501 = 31472604
167 + 31472437 = 31472604
311 + 31472293 = 31472604
313 + 31472291 = 31472604
421 + 31472183 = 31472604

Showing the first eight; more decompositions exist.
