Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462458, here are decompositions:

7 + 31462451 = 31462458
17 + 31462441 = 31462458
19 + 31462439 = 31462458
101 + 31462357 = 31462458
107 + 31462351 = 31462458
109 + 31462349 = 31462458
191 + 31462267 = 31462458
241 + 31462217 = 31462458

Showing the first eight; more decompositions exist.
