Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588226, here are decompositions:

97 + 31588129 = 31588226
139 + 31588087 = 31588226
223 + 31588003 = 31588226
277 + 31587949 = 31588226
283 + 31587943 = 31588226
349 + 31587877 = 31588226
367 + 31587859 = 31588226
409 + 31587817 = 31588226

Showing the first eight; more decompositions exist.
