Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458434, here are decompositions:

3 + 31458431 = 31458434
31 + 31458403 = 31458434
61 + 31458373 = 31458434
103 + 31458331 = 31458434
157 + 31458277 = 31458434
373 + 31458061 = 31458434
421 + 31458013 = 31458434
523 + 31457911 = 31458434

Showing the first eight; more decompositions exist.
