Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462182, here are decompositions:

41 + 31462141 = 31462182
79 + 31462103 = 31462182
113 + 31462069 = 31462182
179 + 31462003 = 31462182
233 + 31461949 = 31462182
239 + 31461943 = 31462182
263 + 31461919 = 31462182
331 + 31461851 = 31462182

Showing the first eight; more decompositions exist.
