Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989158, here are decompositions:

59 + 989099 = 989158
179 + 988979 = 989158
257 + 988901 = 989158
281 + 988877 = 989158
431 + 988727 = 989158
509 + 988649 = 989158
587 + 988571 = 989158
617 + 988541 = 989158

Showing the first eight; more decompositions exist.
