Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458292, here are decompositions:

53 + 31458239 = 31458292
101 + 31458191 = 31458292
179 + 31458113 = 31458292
293 + 31457999 = 31458292
389 + 31457903 = 31458292
431 + 31457861 = 31458292
443 + 31457849 = 31458292
449 + 31457843 = 31458292

Showing the first eight; more decompositions exist.
