Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462470, here are decompositions:

19 + 31462451 = 31462470
29 + 31462441 = 31462470
31 + 31462439 = 31462470
37 + 31462433 = 31462470
89 + 31462381 = 31462470
97 + 31462373 = 31462470
107 + 31462363 = 31462470
113 + 31462357 = 31462470

Showing the first eight; more decompositions exist.
