Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607400, here are decompositions:

37 + 31607363 = 31607400
43 + 31607357 = 31607400
59 + 31607341 = 31607400
73 + 31607327 = 31607400
101 + 31607299 = 31607400
103 + 31607297 = 31607400
107 + 31607293 = 31607400
109 + 31607291 = 31607400

Showing the first eight; more decompositions exist.
