Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461434, here are decompositions:

7 + 31461427 = 31461434
31 + 31461403 = 31461434
73 + 31461361 = 31461434
181 + 31461253 = 31461434
211 + 31461223 = 31461434
241 + 31461193 = 31461434
271 + 31461163 = 31461434
307 + 31461127 = 31461434

Showing the first eight; more decompositions exist.
