Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554706, here are decompositions:

47 + 31554659 = 31554706
89 + 31554617 = 31554706
137 + 31554569 = 31554706
167 + 31554539 = 31554706
179 + 31554527 = 31554706
233 + 31554473 = 31554706
257 + 31554449 = 31554706
419 + 31554287 = 31554706

Showing the first eight; more decompositions exist.
