Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468340, here are decompositions:

3 + 31468337 = 31468340
97 + 31468243 = 31468340
109 + 31468231 = 31468340
139 + 31468201 = 31468340
181 + 31468159 = 31468340
193 + 31468147 = 31468340
313 + 31468027 = 31468340
373 + 31467967 = 31468340

Showing the first eight; more decompositions exist.
