Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454602, here are decompositions:

89 + 31454513 = 31454602
251 + 31454351 = 31454602
281 + 31454321 = 31454602
353 + 31454249 = 31454602
383 + 31454219 = 31454602
401 + 31454201 = 31454602
479 + 31454123 = 31454602
521 + 31454081 = 31454602

Showing the first eight; more decompositions exist.
