Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978002, here are decompositions:

31 + 977971 = 978002
79 + 977923 = 978002
199 + 977803 = 978002
211 + 977791 = 978002
241 + 977761 = 978002
283 + 977719 = 978002
331 + 977671 = 978002
373 + 977629 = 978002

Showing the first eight; more decompositions exist.
