Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535912, here are decompositions:

3 + 31535909 = 31535912
103 + 31535809 = 31535912
241 + 31535671 = 31535912
409 + 31535503 = 31535912
571 + 31535341 = 31535912
601 + 31535311 = 31535912
739 + 31535173 = 31535912
769 + 31535143 = 31535912

Showing the first eight; more decompositions exist.
