Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554798, here are decompositions:

7 + 31554791 = 31554798
59 + 31554739 = 31554798
89 + 31554709 = 31554798
127 + 31554671 = 31554798
131 + 31554667 = 31554798
139 + 31554659 = 31554798
157 + 31554641 = 31554798
167 + 31554631 = 31554798

Showing the first eight; more decompositions exist.
