Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504602, here are decompositions:

11 + 31504591 = 31504602
29 + 31504573 = 31504602
109 + 31504493 = 31504602
149 + 31504453 = 31504602
163 + 31504439 = 31504602
229 + 31504373 = 31504602
251 + 31504351 = 31504602
373 + 31504229 = 31504602

Showing the first eight; more decompositions exist.
