Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70100, here are decompositions:

61 + 70039 = 70100
97 + 70003 = 70100
103 + 69997 = 70100
109 + 69991 = 70100
223 + 69877 = 70100
241 + 69859 = 70100
271 + 69829 = 70100
337 + 69763 = 70100

Showing the first eight; more decompositions exist.
