Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552370, here are decompositions:

19 + 31552351 = 31552370
61 + 31552309 = 31552370
67 + 31552303 = 31552370
163 + 31552207 = 31552370
313 + 31552057 = 31552370
337 + 31552033 = 31552370
373 + 31551997 = 31552370
433 + 31551937 = 31552370

Showing the first eight; more decompositions exist.
