Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462744, here are decompositions:

167 + 31462577 = 31462744
191 + 31462553 = 31462744
197 + 31462547 = 31462744
263 + 31462481 = 31462744
293 + 31462451 = 31462744
311 + 31462433 = 31462744
431 + 31462313 = 31462744
617 + 31462127 = 31462744

Showing the first eight; more decompositions exist.
