Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462214, here are decompositions:

73 + 31462141 = 31462214
193 + 31462021 = 31462214
211 + 31462003 = 31462214
271 + 31461943 = 31462214
373 + 31461841 = 31462214
397 + 31461817 = 31462214
541 + 31461673 = 31462214
643 + 31461571 = 31462214

Showing the first eight; more decompositions exist.
