Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607500, here are decompositions:

11 + 31607489 = 31607500
53 + 31607447 = 31607500
101 + 31607399 = 31607500
137 + 31607363 = 31607500
173 + 31607327 = 31607500
191 + 31607309 = 31607500
263 + 31607237 = 31607500
293 + 31607207 = 31607500

Showing the first eight; more decompositions exist.
