Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605002, here are decompositions:

43 + 31604959 = 31605002
139 + 31604863 = 31605002
199 + 31604803 = 31605002
271 + 31604731 = 31605002
283 + 31604719 = 31605002
313 + 31604689 = 31605002
619 + 31604383 = 31605002
631 + 31604371 = 31605002

Showing the first eight; more decompositions exist.
