Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582292, here are decompositions:

43 + 31582249 = 31582292
109 + 31582183 = 31582292
199 + 31582093 = 31582292
271 + 31582021 = 31582292
331 + 31581961 = 31582292
409 + 31581883 = 31582292
433 + 31581859 = 31582292
499 + 31581793 = 31582292

Showing the first eight; more decompositions exist.
