Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528934, here are decompositions:

103 + 31528831 = 31528934
127 + 31528807 = 31528934
193 + 31528741 = 31528934
211 + 31528723 = 31528934
313 + 31528621 = 31528934
433 + 31528501 = 31528934
487 + 31528447 = 31528934
571 + 31528363 = 31528934

Showing the first eight; more decompositions exist.
