Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582192, here are decompositions:

29 + 31582163 = 31582192
71 + 31582121 = 31582192
149 + 31582043 = 31582192
281 + 31581911 = 31582192
311 + 31581881 = 31582192
431 + 31581761 = 31582192
461 + 31581731 = 31582192
491 + 31581701 = 31582192

Showing the first eight; more decompositions exist.
