Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449462, here are decompositions:

13 + 31449449 = 31449462
41 + 31449421 = 31449462
53 + 31449409 = 31449462
59 + 31449403 = 31449462
61 + 31449401 = 31449462
89 + 31449373 = 31449462
101 + 31449361 = 31449462
103 + 31449359 = 31449462

Showing the first eight; more decompositions exist.
