Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494432, here are decompositions:

5 + 31494427 = 31494432
31 + 31494401 = 31494432
43 + 31494389 = 31494432
131 + 31494301 = 31494432
139 + 31494293 = 31494432
191 + 31494241 = 31494432
271 + 31494161 = 31494432
313 + 31494119 = 31494432

Showing the first eight; more decompositions exist.
