Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489464, here are decompositions:

31 + 31489433 = 31489464
37 + 31489427 = 31489464
47 + 31489417 = 31489464
53 + 31489411 = 31489464
73 + 31489391 = 31489464
101 + 31489363 = 31489464
271 + 31489193 = 31489464
283 + 31489181 = 31489464

Showing the first eight; more decompositions exist.
