Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604902, here are decompositions:

53 + 31604849 = 31604902
113 + 31604789 = 31604902
179 + 31604723 = 31604902
293 + 31604609 = 31604902
401 + 31604501 = 31604902
449 + 31604453 = 31604902
599 + 31604303 = 31604902
683 + 31604219 = 31604902

Showing the first eight; more decompositions exist.
