Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529222, here are decompositions:

3 + 31529219 = 31529222
73 + 31529149 = 31529222
229 + 31528993 = 31529222
313 + 31528909 = 31529222
379 + 31528843 = 31529222
409 + 31528813 = 31529222
421 + 31528801 = 31529222
499 + 31528723 = 31529222

Showing the first eight; more decompositions exist.
