Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463842, here are decompositions:

83 + 31463759 = 31463842
251 + 31463591 = 31463842
353 + 31463489 = 31463842
359 + 31463483 = 31463842
383 + 31463459 = 31463842
479 + 31463363 = 31463842
521 + 31463321 = 31463842
593 + 31463249 = 31463842

Showing the first eight; more decompositions exist.
