Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458174, here are decompositions:

5 + 31458169 = 31458174
43 + 31458131 = 31458174
61 + 31458113 = 31458174
113 + 31458061 = 31458174
263 + 31457911 = 31458174
271 + 31457903 = 31458174
313 + 31457861 = 31458174
317 + 31457857 = 31458174

Showing the first eight; more decompositions exist.
