Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496430, here are decompositions:

11 + 31496419 = 31496430
13 + 31496417 = 31496430
41 + 31496389 = 31496430
59 + 31496371 = 31496430
61 + 31496369 = 31496430
101 + 31496329 = 31496430
109 + 31496321 = 31496430
113 + 31496317 = 31496430

Showing the first eight; more decompositions exist.
