Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604602, here are decompositions:

41 + 31604561 = 31604602
101 + 31604501 = 31604602
149 + 31604453 = 31604602
383 + 31604219 = 31604602
503 + 31604099 = 31604602
569 + 31604033 = 31604602
683 + 31603919 = 31604602
773 + 31603829 = 31604602

Showing the first eight; more decompositions exist.
