Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607144, here are decompositions:

7 + 31607137 = 31607144
43 + 31607101 = 31607144
97 + 31607047 = 31607144
181 + 31606963 = 31607144
193 + 31606951 = 31607144
241 + 31606903 = 31607144
433 + 31606711 = 31607144
463 + 31606681 = 31607144

Showing the first eight; more decompositions exist.
