Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541890, here are decompositions:

31 + 541859 = 541890
53 + 541837 = 541890
59 + 541831 = 541890
73 + 541817 = 541890
109 + 541781 = 541890
113 + 541777 = 541890
127 + 541763 = 541890
131 + 541759 = 541890

Showing the first eight; more decompositions exist.
