Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552670, here are decompositions:

31 + 31552639 = 31552670
67 + 31552603 = 31552670
181 + 31552489 = 31552670
241 + 31552429 = 31552670
277 + 31552393 = 31552670
283 + 31552387 = 31552670
367 + 31552303 = 31552670
433 + 31552237 = 31552670

Showing the first eight; more decompositions exist.
