Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470692, here are decompositions:

31 + 31470661 = 31470692
73 + 31470619 = 31470692
223 + 31470469 = 31470692
283 + 31470409 = 31470692
313 + 31470379 = 31470692
433 + 31470259 = 31470692
499 + 31470193 = 31470692
541 + 31470151 = 31470692

Showing the first eight; more decompositions exist.
