Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552382, here are decompositions:

31 + 31552351 = 31552382
73 + 31552309 = 31552382
79 + 31552303 = 31552382
313 + 31552069 = 31552382
349 + 31552033 = 31552382
523 + 31551859 = 31552382
601 + 31551781 = 31552382
661 + 31551721 = 31552382

Showing the first eight; more decompositions exist.
