Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489462, here are decompositions:

29 + 31489433 = 31489462
71 + 31489391 = 31489462
113 + 31489349 = 31489462
233 + 31489229 = 31489462
269 + 31489193 = 31489462
281 + 31489181 = 31489462
293 + 31489169 = 31489462
383 + 31489079 = 31489462

Showing the first eight; more decompositions exist.
