Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588444, here are decompositions:

3 + 31588441 = 31588444
5 + 31588439 = 31588444
113 + 31588331 = 31588444
131 + 31588313 = 31588444
137 + 31588307 = 31588444
191 + 31588253 = 31588444
197 + 31588247 = 31588444
383 + 31588061 = 31588444

Showing the first eight; more decompositions exist.
