Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599426, here are decompositions:

37 + 31599389 = 31599426
73 + 31599353 = 31599426
113 + 31599313 = 31599426
167 + 31599259 = 31599426
179 + 31599247 = 31599426
233 + 31599193 = 31599426
269 + 31599157 = 31599426
367 + 31599059 = 31599426

Showing the first eight; more decompositions exist.
