Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620338, here are decompositions:

37 + 31620301 = 31620338
109 + 31620229 = 31620338
199 + 31620139 = 31620338
229 + 31620109 = 31620338
271 + 31620067 = 31620338
349 + 31619989 = 31620338
577 + 31619761 = 31620338
691 + 31619647 = 31620338

Showing the first eight; more decompositions exist.
