Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489476, here are decompositions:

13 + 31489463 = 31489476
43 + 31489433 = 31489476
59 + 31489417 = 31489476
113 + 31489363 = 31489476
127 + 31489349 = 31489476
197 + 31489279 = 31489476
229 + 31489247 = 31489476
233 + 31489243 = 31489476

Showing the first eight; more decompositions exist.
