Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532722, here are decompositions:

29 + 31532693 = 31532722
83 + 31532639 = 31532722
149 + 31532573 = 31532722
233 + 31532489 = 31532722
293 + 31532429 = 31532722
383 + 31532339 = 31532722
443 + 31532279 = 31532722
461 + 31532261 = 31532722

Showing the first eight; more decompositions exist.
