Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492786, here are decompositions:

433 + 2147492353 = 2147492786
457 + 2147492329 = 2147492786
487 + 2147492299 = 2147492786
547 + 2147492239 = 2147492786
757 + 2147492029 = 2147492786
883 + 2147491903 = 2147492786
1087 + 2147491699 = 2147492786
1213 + 2147491573 = 2147492786

Showing the first eight; more decompositions exist.
