Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470496, here are decompositions:

53 + 31470443 = 31470496
137 + 31470359 = 31470496
173 + 31470323 = 31470496
353 + 31470143 = 31470496
509 + 31469987 = 31470496
593 + 31469903 = 31470496
647 + 31469849 = 31470496
683 + 31469813 = 31470496

Showing the first eight; more decompositions exist.
