Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492588, here are decompositions:

11 + 31492577 = 31492588
47 + 31492541 = 31492588
59 + 31492529 = 31492588
167 + 31492421 = 31492588
251 + 31492337 = 31492588
269 + 31492319 = 31492588
311 + 31492277 = 31492588
431 + 31492157 = 31492588

Showing the first eight; more decompositions exist.
