Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528696, here are decompositions:

83 + 31528613 = 31528696
137 + 31528559 = 31528696
149 + 31528547 = 31528696
197 + 31528499 = 31528696
263 + 31528433 = 31528696
347 + 31528349 = 31528696
359 + 31528337 = 31528696
383 + 31528313 = 31528696

Showing the first eight; more decompositions exist.
