Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569064, here are decompositions:

5 + 31569059 = 31569064
167 + 31568897 = 31569064
503 + 31568561 = 31569064
521 + 31568543 = 31569064
641 + 31568423 = 31569064
647 + 31568417 = 31569064
677 + 31568387 = 31569064
797 + 31568267 = 31569064

Showing the first eight; more decompositions exist.
