Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528534, here are decompositions:

3 + 31528531 = 31528534
83 + 31528451 = 31528534
101 + 31528433 = 31528534
197 + 31528337 = 31528534
251 + 31528283 = 31528534
293 + 31528241 = 31528534
383 + 31528151 = 31528534
431 + 31528103 = 31528534

Showing the first eight; more decompositions exist.
