Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489214, here are decompositions:

37 + 31489177 = 31489214
67 + 31489147 = 31489214
151 + 31489063 = 31489214
223 + 31488991 = 31489214
283 + 31488931 = 31489214
307 + 31488907 = 31489214
733 + 31488481 = 31489214
751 + 31488463 = 31489214

Showing the first eight; more decompositions exist.
