Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542598, here are decompositions:

11 + 31542587 = 31542598
89 + 31542509 = 31542598
179 + 31542419 = 31542598
239 + 31542359 = 31542598
257 + 31542341 = 31542598
317 + 31542281 = 31542598
401 + 31542197 = 31542598
449 + 31542149 = 31542598

Showing the first eight; more decompositions exist.
