Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461926, here are decompositions:

3 + 31461923 = 31461926
7 + 31461919 = 31461926
103 + 31461823 = 31461926
109 + 31461817 = 31461926
163 + 31461763 = 31461926
229 + 31461697 = 31461926
373 + 31461553 = 31461926
409 + 31461517 = 31461926

Showing the first eight; more decompositions exist.
