Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495954, here are decompositions:

5 + 31495949 = 31495954
107 + 31495847 = 31495954
197 + 31495757 = 31495954
263 + 31495691 = 31495954
293 + 31495661 = 31495954
353 + 31495601 = 31495954
431 + 31495523 = 31495954
443 + 31495511 = 31495954

Showing the first eight; more decompositions exist.
