Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499734, here are decompositions:

3 + 31499731 = 31499734
23 + 31499711 = 31499734
113 + 31499621 = 31499734
173 + 31499561 = 31499734
197 + 31499537 = 31499734
347 + 31499387 = 31499734
443 + 31499291 = 31499734
467 + 31499267 = 31499734

Showing the first eight; more decompositions exist.
