Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598242, here are decompositions:

3 + 31598239 = 31598242
29 + 31598213 = 31598242
41 + 31598201 = 31598242
101 + 31598141 = 31598242
233 + 31598009 = 31598242
281 + 31597961 = 31598242
419 + 31597823 = 31598242
449 + 31597793 = 31598242

Showing the first eight; more decompositions exist.
