Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454262, here are decompositions:

13 + 31454249 = 31454262
41 + 31454221 = 31454262
43 + 31454219 = 31454262
61 + 31454201 = 31454262
71 + 31454191 = 31454262
101 + 31454161 = 31454262
113 + 31454149 = 31454262
139 + 31454123 = 31454262

Showing the first eight; more decompositions exist.
