Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599382, here are decompositions:

29 + 31599353 = 31599382
41 + 31599341 = 31599382
281 + 31599101 = 31599382
443 + 31598939 = 31599382
449 + 31598933 = 31599382
509 + 31598873 = 31599382
593 + 31598789 = 31599382
599 + 31598783 = 31599382

Showing the first eight; more decompositions exist.
