Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552826, here are decompositions:

79 + 31552747 = 31552826
223 + 31552603 = 31552826
337 + 31552489 = 31552826
397 + 31552429 = 31552826
433 + 31552393 = 31552826
439 + 31552387 = 31552826
523 + 31552303 = 31552826
619 + 31552207 = 31552826

Showing the first eight; more decompositions exist.
