Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558274, here are decompositions:

67 + 31558207 = 31558274
127 + 31558147 = 31558274
193 + 31558081 = 31558274
211 + 31558063 = 31558274
277 + 31557997 = 31558274
313 + 31557961 = 31558274
337 + 31557937 = 31558274
463 + 31557811 = 31558274

Showing the first eight; more decompositions exist.
