Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528498, here are decompositions:

47 + 31528451 = 31528498
149 + 31528349 = 31528498
257 + 31528241 = 31528498
269 + 31528229 = 31528498
347 + 31528151 = 31528498
431 + 31528067 = 31528498
461 + 31528037 = 31528498
479 + 31528019 = 31528498

Showing the first eight; more decompositions exist.
