Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489614, here are decompositions:

43 + 31489571 = 31489614
73 + 31489541 = 31489614
151 + 31489463 = 31489614
181 + 31489433 = 31489614
197 + 31489417 = 31489614
223 + 31489391 = 31489614
251 + 31489363 = 31489614
367 + 31489247 = 31489614

Showing the first eight; more decompositions exist.
