Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541990, here are decompositions:

3 + 541987 = 541990
23 + 541967 = 541990
89 + 541901 = 541990
101 + 541889 = 541990
131 + 541859 = 541990
173 + 541817 = 541990
191 + 541799 = 541990
227 + 541763 = 541990

Showing the first eight; more decompositions exist.
