Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501444, here are decompositions:

11 + 31501433 = 31501444
17 + 31501427 = 31501444
41 + 31501403 = 31501444
83 + 31501361 = 31501444
113 + 31501331 = 31501444
131 + 31501313 = 31501444
197 + 31501247 = 31501444
353 + 31501091 = 31501444

Showing the first eight; more decompositions exist.
