Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495848, here are decompositions:

29 + 31495819 = 31495848
47 + 31495801 = 31495848
107 + 31495741 = 31495848
157 + 31495691 = 31495848
191 + 31495657 = 31495848
257 + 31495591 = 31495848
331 + 31495517 = 31495848
337 + 31495511 = 31495848

Showing the first eight; more decompositions exist.
