Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590952, here are decompositions:

11 + 31590941 = 31590952
23 + 31590929 = 31590952
53 + 31590899 = 31590952
59 + 31590893 = 31590952
149 + 31590803 = 31590952
269 + 31590683 = 31590952
293 + 31590659 = 31590952
359 + 31590593 = 31590952

Showing the first eight; more decompositions exist.
