Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574722, here are decompositions:

29 + 31574693 = 31574722
41 + 31574681 = 31574722
83 + 31574639 = 31574722
191 + 31574531 = 31574722
233 + 31574489 = 31574722
269 + 31574453 = 31574722
293 + 31574429 = 31574722
353 + 31574369 = 31574722

Showing the first eight; more decompositions exist.
