Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462450, here are decompositions:

11 + 31462439 = 31462450
17 + 31462433 = 31462450
101 + 31462349 = 31462450
137 + 31462313 = 31462450
233 + 31462217 = 31462450
317 + 31462133 = 31462450
347 + 31462103 = 31462450
443 + 31462007 = 31462450

Showing the first eight; more decompositions exist.
