Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471604, here are decompositions:

13 + 31471591 = 31471604
193 + 31471411 = 31471604
397 + 31471207 = 31471604
433 + 31471171 = 31471604
457 + 31471147 = 31471604
607 + 31470997 = 31471604
613 + 31470991 = 31471604
691 + 31470913 = 31471604

Showing the first eight; more decompositions exist.
