Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544530, here are decompositions:

113 + 31544417 = 31544530
137 + 31544393 = 31544530
167 + 31544363 = 31544530
233 + 31544297 = 31544530
317 + 31544213 = 31544530
359 + 31544171 = 31544530
431 + 31544099 = 31544530
491 + 31544039 = 31544530

Showing the first eight; more decompositions exist.
