Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494846, here are decompositions:

29 + 31494817 = 31494846
37 + 31494809 = 31494846
79 + 31494767 = 31494846
83 + 31494763 = 31494846
109 + 31494737 = 31494846
139 + 31494707 = 31494846
157 + 31494689 = 31494846
167 + 31494679 = 31494846

Showing the first eight; more decompositions exist.
