Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554658, here are decompositions:

17 + 31554641 = 31554658
41 + 31554617 = 31554658
89 + 31554569 = 31554658
131 + 31554527 = 31554658
257 + 31554401 = 31554658
479 + 31554179 = 31554658
647 + 31554011 = 31554658
857 + 31553801 = 31554658

Showing the first eight; more decompositions exist.
