Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552868, here are decompositions:

37 + 31552831 = 31552868
229 + 31552639 = 31552868
331 + 31552537 = 31552868
379 + 31552489 = 31552868
439 + 31552429 = 31552868
631 + 31552237 = 31552868
661 + 31552207 = 31552868
811 + 31552057 = 31552868

Showing the first eight; more decompositions exist.
