Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568476, here are decompositions:

53 + 31568423 = 31568476
59 + 31568417 = 31568476
83 + 31568393 = 31568476
89 + 31568387 = 31568476
167 + 31568309 = 31568476
179 + 31568297 = 31568476
347 + 31568129 = 31568476
353 + 31568123 = 31568476

Showing the first eight; more decompositions exist.
