Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003812, here are decompositions:

41 + 1003771 = 1003812
59 + 1003753 = 1003812
71 + 1003741 = 1003812
79 + 1003733 = 1003812
83 + 1003729 = 1003812
101 + 1003711 = 1003812
181 + 1003631 = 1003812
191 + 1003621 = 1003812

Showing the first eight; more decompositions exist.
