Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581126, here are decompositions:

37 + 581089 = 581126
79 + 581047 = 581126
97 + 581029 = 581126
157 + 580969 = 581126
199 + 580927 = 581126
283 + 580843 = 581126
313 + 580813 = 581126
367 + 580759 = 581126

Showing the first eight; more decompositions exist.
