Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582700, here are decompositions:

67 + 31582633 = 31582700
73 + 31582627 = 31582700
211 + 31582489 = 31582700
229 + 31582471 = 31582700
283 + 31582417 = 31582700
367 + 31582333 = 31582700
379 + 31582321 = 31582700
433 + 31582267 = 31582700

Showing the first eight; more decompositions exist.
