Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582756, here are decompositions:

17 + 31582739 = 31582756
83 + 31582673 = 31582756
89 + 31582667 = 31582756
167 + 31582589 = 31582756
197 + 31582559 = 31582756
347 + 31582409 = 31582756
353 + 31582403 = 31582756
419 + 31582337 = 31582756

Showing the first eight; more decompositions exist.
