Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462330, here are decompositions:

17 + 31462313 = 31462330
41 + 31462289 = 31462330
113 + 31462217 = 31462330
197 + 31462133 = 31462330
227 + 31462103 = 31462330
353 + 31461977 = 31462330
443 + 31461887 = 31462330
479 + 31461851 = 31462330

Showing the first eight; more decompositions exist.
