Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462462, here are decompositions:

11 + 31462451 = 31462462
23 + 31462439 = 31462462
29 + 31462433 = 31462462
89 + 31462373 = 31462462
113 + 31462349 = 31462462
149 + 31462313 = 31462462
173 + 31462289 = 31462462
359 + 31462103 = 31462462

Showing the first eight; more decompositions exist.
