Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528754, here are decompositions:

3 + 31528751 = 31528754
13 + 31528741 = 31528754
31 + 31528723 = 31528754
181 + 31528573 = 31528754
223 + 31528531 = 31528754
307 + 31528447 = 31528754
463 + 31528291 = 31528754
487 + 31528267 = 31528754

Showing the first eight; more decompositions exist.
