Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462190, here are decompositions:

211 + 31461979 = 31462190
229 + 31461961 = 31462190
241 + 31461949 = 31462190
271 + 31461919 = 31462190
349 + 31461841 = 31462190
367 + 31461823 = 31462190
373 + 31461817 = 31462190
379 + 31461811 = 31462190

Showing the first eight; more decompositions exist.
