Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450054, here are decompositions:

11 + 31450043 = 31450054
23 + 31450031 = 31450054
131 + 31449923 = 31450054
263 + 31449791 = 31450054
353 + 31449701 = 31450054
443 + 31449611 = 31450054
653 + 31449401 = 31450054
677 + 31449377 = 31450054

Showing the first eight; more decompositions exist.
