Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461798, here are decompositions:

7 + 31461791 = 31461798
19 + 31461779 = 31461798
37 + 31461761 = 31461798
61 + 31461737 = 31461798
101 + 31461697 = 31461798
157 + 31461641 = 31461798
227 + 31461571 = 31461798
229 + 31461569 = 31461798

Showing the first eight; more decompositions exist.
