Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462718, here are decompositions:

109 + 31462609 = 31462718
127 + 31462591 = 31462718
139 + 31462579 = 31462718
211 + 31462507 = 31462718
277 + 31462441 = 31462718
337 + 31462381 = 31462718
367 + 31462351 = 31462718
379 + 31462339 = 31462718

Showing the first eight; more decompositions exist.
