Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581302, here are decompositions:

41 + 581261 = 581302
101 + 581201 = 581302
131 + 581171 = 581302
233 + 581069 = 581302
383 + 580919 = 581302
389 + 580913 = 581302
401 + 580901 = 581302
431 + 580871 = 581302

Showing the first eight; more decompositions exist.
