Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582604, here are decompositions:

3 + 31582601 = 31582604
73 + 31582531 = 31582604
271 + 31582333 = 31582604
283 + 31582321 = 31582604
337 + 31582267 = 31582604
397 + 31582207 = 31582604
421 + 31582183 = 31582604
433 + 31582171 = 31582604

Showing the first eight; more decompositions exist.
