Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494926, here are decompositions:

3 + 31494923 = 31494926
7 + 31494919 = 31494926
19 + 31494907 = 31494926
109 + 31494817 = 31494926
157 + 31494769 = 31494926
163 + 31494763 = 31494926
283 + 31494643 = 31494926
373 + 31494553 = 31494926

Showing the first eight; more decompositions exist.
