Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462202, here are decompositions:

61 + 31462141 = 31462202
181 + 31462021 = 31462202
199 + 31462003 = 31462202
223 + 31461979 = 31462202
241 + 31461961 = 31462202
283 + 31461919 = 31462202
379 + 31461823 = 31462202
439 + 31461763 = 31462202

Showing the first eight; more decompositions exist.
