Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540706, here are decompositions:

7 + 31540699 = 31540706
13 + 31540693 = 31540706
37 + 31540669 = 31540706
367 + 31540339 = 31540706
397 + 31540309 = 31540706
409 + 31540297 = 31540706
499 + 31540207 = 31540706
607 + 31540099 = 31540706

Showing the first eight; more decompositions exist.
