Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545002, here are decompositions:

61 + 31544941 = 31545002
79 + 31544923 = 31545002
103 + 31544899 = 31545002
283 + 31544719 = 31545002
631 + 31544371 = 31545002
691 + 31544311 = 31545002
823 + 31544179 = 31545002
991 + 31544011 = 31545002

Showing the first eight; more decompositions exist.
