Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540926, here are decompositions:

5 + 31540921 = 31540926
59 + 31540867 = 31540926
89 + 31540837 = 31540926
103 + 31540823 = 31540926
113 + 31540813 = 31540926
139 + 31540787 = 31540926
199 + 31540727 = 31540926
227 + 31540699 = 31540926

Showing the first eight; more decompositions exist.
