Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743812, here are decompositions:

5 + 8743807 = 8743812
41 + 8743771 = 8743812
43 + 8743769 = 8743812
59 + 8743753 = 8743812
79 + 8743733 = 8743812
101 + 8743711 = 8743812
131 + 8743681 = 8743812
139 + 8743673 = 8743812

Showing the first eight; more decompositions exist.
