Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552346, here are decompositions:

37 + 31552309 = 31552346
43 + 31552303 = 31552346
109 + 31552237 = 31552346
139 + 31552207 = 31552346
277 + 31552069 = 31552346
313 + 31552033 = 31552346
349 + 31551997 = 31552346
367 + 31551979 = 31552346

Showing the first eight; more decompositions exist.
