Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489498, here are decompositions:

71 + 31489427 = 31489498
107 + 31489391 = 31489498
149 + 31489349 = 31489498
239 + 31489259 = 31489498
251 + 31489247 = 31489498
269 + 31489229 = 31489498
281 + 31489217 = 31489498
317 + 31489181 = 31489498

Showing the first eight; more decompositions exist.
