Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468358, here are decompositions:

127 + 31468231 = 31468358
157 + 31468201 = 31468358
199 + 31468159 = 31468358
211 + 31468147 = 31468358
331 + 31468027 = 31468358
409 + 31467949 = 31468358
421 + 31467937 = 31468358
547 + 31467811 = 31468358

Showing the first eight; more decompositions exist.
