Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552946, here are decompositions:

3 + 31552943 = 31552946
67 + 31552879 = 31552946
199 + 31552747 = 31552946
307 + 31552639 = 31552946
367 + 31552579 = 31552946
409 + 31552537 = 31552946
457 + 31552489 = 31552946
643 + 31552303 = 31552946

Showing the first eight; more decompositions exist.
