Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462452, here are decompositions:

11 + 31462441 = 31462452
13 + 31462439 = 31462452
19 + 31462433 = 31462452
71 + 31462381 = 31462452
79 + 31462373 = 31462452
89 + 31462363 = 31462452
101 + 31462351 = 31462452
103 + 31462349 = 31462452

Showing the first eight; more decompositions exist.
