Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552766, here are decompositions:

19 + 31552747 = 31552766
73 + 31552693 = 31552766
127 + 31552639 = 31552766
163 + 31552603 = 31552766
229 + 31552537 = 31552766
277 + 31552489 = 31552766
337 + 31552429 = 31552766
373 + 31552393 = 31552766

Showing the first eight; more decompositions exist.
