Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582024, here are decompositions:

3 + 31582021 = 31582024
41 + 31581983 = 31582024
113 + 31581911 = 31582024
263 + 31581761 = 31582024
293 + 31581731 = 31582024
317 + 31581707 = 31582024
347 + 31581677 = 31582024
401 + 31581623 = 31582024

Showing the first eight; more decompositions exist.
