Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462184, here are decompositions:

43 + 31462141 = 31462184
163 + 31462021 = 31462184
181 + 31462003 = 31462184
223 + 31461961 = 31462184
241 + 31461943 = 31462184
367 + 31461817 = 31462184
373 + 31461811 = 31462184
421 + 31461763 = 31462184

Showing the first eight; more decompositions exist.
