Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624214, here are decompositions:

67 + 31624147 = 31624214
73 + 31624141 = 31624214
211 + 31624003 = 31624214
283 + 31623931 = 31624214
313 + 31623901 = 31624214
397 + 31623817 = 31624214
547 + 31623667 = 31624214
607 + 31623607 = 31624214

Showing the first eight; more decompositions exist.
