Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470526, here are decompositions:

83 + 31470443 = 31470526
167 + 31470359 = 31470526
173 + 31470353 = 31470526
233 + 31470293 = 31470526
317 + 31470209 = 31470526
359 + 31470167 = 31470526
383 + 31470143 = 31470526
677 + 31469849 = 31470526

Showing the first eight; more decompositions exist.
