Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454622, here are decompositions:

109 + 31454513 = 31454622
139 + 31454483 = 31454622
181 + 31454441 = 31454622
191 + 31454431 = 31454622
233 + 31454389 = 31454622
239 + 31454383 = 31454622
271 + 31454351 = 31454622
359 + 31454263 = 31454622

Showing the first eight; more decompositions exist.
