Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552148, here are decompositions:

79 + 31552069 = 31552148
151 + 31551997 = 31552148
211 + 31551937 = 31552148
367 + 31551781 = 31552148
571 + 31551577 = 31552148
601 + 31551547 = 31552148
631 + 31551517 = 31552148
739 + 31551409 = 31552148

Showing the first eight; more decompositions exist.
