Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554038, here are decompositions:

277 + 31553761 = 31554038
331 + 31553707 = 31554038
367 + 31553671 = 31554038
379 + 31553659 = 31554038
421 + 31553617 = 31554038
877 + 31553161 = 31554038
1021 + 31553017 = 31554038
1039 + 31552999 = 31554038

Showing the first eight; more decompositions exist.
