Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461342, here are decompositions:

41 + 31461301 = 31461342
61 + 31461281 = 31461342
89 + 31461253 = 31461342
113 + 31461229 = 31461342
149 + 31461193 = 31461342
151 + 31461191 = 31461342
163 + 31461179 = 31461342
179 + 31461163 = 31461342

Showing the first eight; more decompositions exist.
