Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460894, here are decompositions:

43 + 31460851 = 31460894
61 + 31460833 = 31460894
103 + 31460791 = 31460894
151 + 31460743 = 31460894
193 + 31460701 = 31460894
313 + 31460581 = 31460894
397 + 31460497 = 31460894
463 + 31460431 = 31460894

Showing the first eight; more decompositions exist.
