Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624276, here are decompositions:

59 + 31624217 = 31624276
149 + 31624127 = 31624276
263 + 31624013 = 31624276
293 + 31623983 = 31624276
317 + 31623959 = 31624276
347 + 31623929 = 31624276
389 + 31623887 = 31624276
419 + 31623857 = 31624276

Showing the first eight; more decompositions exist.
