Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603602, here are decompositions:

83 + 31603519 = 31603602
113 + 31603489 = 31603602
241 + 31603361 = 31603602
293 + 31603309 = 31603602
353 + 31603249 = 31603602
409 + 31603193 = 31603602
461 + 31603141 = 31603602
463 + 31603139 = 31603602

Showing the first eight; more decompositions exist.
