Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541690, here are decompositions:

29 + 541661 = 541690
59 + 541631 = 541690
101 + 541589 = 541690
113 + 541577 = 541690
167 + 541523 = 541690
179 + 541511 = 541690
251 + 541439 = 541690
389 + 541301 = 541690

Showing the first eight; more decompositions exist.
