Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492026, here are decompositions:

37 + 31491989 = 31492026
43 + 31491983 = 31492026
67 + 31491959 = 31492026
109 + 31491917 = 31492026
113 + 31491913 = 31492026
233 + 31491793 = 31492026
239 + 31491787 = 31492026
277 + 31491749 = 31492026

Showing the first eight; more decompositions exist.
