Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506602, here are decompositions:

3 + 31506599 = 31506602
73 + 31506529 = 31506602
79 + 31506523 = 31506602
181 + 31506421 = 31506602
229 + 31506373 = 31506602
271 + 31506331 = 31506602
331 + 31506271 = 31506602
409 + 31506193 = 31506602

Showing the first eight; more decompositions exist.
