Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600742, here are decompositions:

73 + 31600669 = 31600742
79 + 31600663 = 31600742
193 + 31600549 = 31600742
211 + 31600531 = 31600742
409 + 31600333 = 31600742
463 + 31600279 = 31600742
541 + 31600201 = 31600742
643 + 31600099 = 31600742

Showing the first eight; more decompositions exist.
