Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498312, here are decompositions:

5 + 31498307 = 31498312
23 + 31498289 = 31498312
59 + 31498253 = 31498312
113 + 31498199 = 31498312
269 + 31498043 = 31498312
383 + 31497929 = 31498312
449 + 31497863 = 31498312
509 + 31497803 = 31498312

Showing the first eight; more decompositions exist.
