Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462392, here are decompositions:

11 + 31462381 = 31462392
19 + 31462373 = 31462392
29 + 31462363 = 31462392
41 + 31462351 = 31462392
43 + 31462349 = 31462392
53 + 31462339 = 31462392
79 + 31462313 = 31462392
103 + 31462289 = 31462392

Showing the first eight; more decompositions exist.
