Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450192, here are decompositions:

29 + 31450163 = 31450192
89 + 31450103 = 31450192
131 + 31450061 = 31450192
149 + 31450043 = 31450192
269 + 31449923 = 31450192
401 + 31449791 = 31450192
491 + 31449701 = 31450192
503 + 31449689 = 31450192

Showing the first eight; more decompositions exist.
