Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582826, here are decompositions:

3 + 31582823 = 31582826
7 + 31582819 = 31582826
97 + 31582729 = 31582826
193 + 31582633 = 31582826
199 + 31582627 = 31582826
313 + 31582513 = 31582826
337 + 31582489 = 31582826
409 + 31582417 = 31582826

Showing the first eight; more decompositions exist.
