Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553330, here are decompositions:

97 + 31553233 = 31553330
241 + 31553089 = 31553330
313 + 31553017 = 31553330
331 + 31552999 = 31553330
439 + 31552891 = 31553330
499 + 31552831 = 31553330
691 + 31552639 = 31553330
709 + 31552621 = 31553330

Showing the first eight; more decompositions exist.
