Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489486, here are decompositions:

23 + 31489463 = 31489486
53 + 31489433 = 31489486
59 + 31489427 = 31489486
137 + 31489349 = 31489486
227 + 31489259 = 31489486
239 + 31489247 = 31489486
257 + 31489229 = 31489486
269 + 31489217 = 31489486

Showing the first eight; more decompositions exist.
