Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541988, here are decompositions:

37 + 541951 = 541988
61 + 541927 = 541988
151 + 541837 = 541988
157 + 541831 = 541988
211 + 541777 = 541988
229 + 541759 = 541988
277 + 541711 = 541988
331 + 541657 = 541988

Showing the first eight; more decompositions exist.
