Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532380, here are decompositions:

41 + 31532339 = 31532380
101 + 31532279 = 31532380
239 + 31532141 = 31532380
263 + 31532117 = 31532380
317 + 31532063 = 31532380
359 + 31532021 = 31532380
449 + 31531931 = 31532380
563 + 31531817 = 31532380

Showing the first eight; more decompositions exist.
