Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540600, here are decompositions:

71 + 31540529 = 31540600
101 + 31540499 = 31540600
107 + 31540493 = 31540600
257 + 31540343 = 31540600
359 + 31540241 = 31540600
383 + 31540217 = 31540600
389 + 31540211 = 31540600
419 + 31540181 = 31540600

Showing the first eight; more decompositions exist.
