Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454292, here are decompositions:

29 + 31454263 = 31454292
43 + 31454249 = 31454292
71 + 31454221 = 31454292
73 + 31454219 = 31454292
101 + 31454191 = 31454292
131 + 31454161 = 31454292
211 + 31454081 = 31454292
239 + 31454053 = 31454292

Showing the first eight; more decompositions exist.
