Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534256, here are decompositions:

73 + 31534183 = 31534256
139 + 31534117 = 31534256
199 + 31534057 = 31534256
223 + 31534033 = 31534256
277 + 31533979 = 31534256
307 + 31533949 = 31534256
337 + 31533919 = 31534256
409 + 31533847 = 31534256

Showing the first eight; more decompositions exist.
