Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972538, here are decompositions:

97 + 4294972441 = 4294972538
127 + 4294972411 = 4294972538
271 + 4294972267 = 4294972538
331 + 4294972207 = 4294972538
421 + 4294972117 = 4294972538
487 + 4294972051 = 4294972538
499 + 4294972039 = 4294972538
547 + 4294971991 = 4294972538

Showing the first eight; more decompositions exist.
