Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552376, here are decompositions:

67 + 31552309 = 31552376
73 + 31552303 = 31552376
139 + 31552237 = 31552376
307 + 31552069 = 31552376
379 + 31551997 = 31552376
397 + 31551979 = 31552376
439 + 31551937 = 31552376
523 + 31551853 = 31552376

Showing the first eight; more decompositions exist.
