Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547722, here are decompositions:

29 + 31547693 = 31547722
113 + 31547609 = 31547722
131 + 31547591 = 31547722
191 + 31547531 = 31547722
233 + 31547489 = 31547722
251 + 31547471 = 31547722
263 + 31547459 = 31547722
281 + 31547441 = 31547722

Showing the first eight; more decompositions exist.
