Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589336, here are decompositions:

3 + 31589333 = 31589336
7 + 31589329 = 31589336
19 + 31589317 = 31589336
43 + 31589293 = 31589336
139 + 31589197 = 31589336
199 + 31589137 = 31589336
379 + 31588957 = 31589336
409 + 31588927 = 31589336

Showing the first eight; more decompositions exist.
