Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582892, here are decompositions:

73 + 31582819 = 31582892
163 + 31582729 = 31582892
283 + 31582609 = 31582892
379 + 31582513 = 31582892
421 + 31582471 = 31582892
571 + 31582321 = 31582892
643 + 31582249 = 31582892
709 + 31582183 = 31582892

Showing the first eight; more decompositions exist.
