Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462402, here are decompositions:

29 + 31462373 = 31462402
53 + 31462349 = 31462402
89 + 31462313 = 31462402
113 + 31462289 = 31462402
269 + 31462133 = 31462402
479 + 31461923 = 31462402
509 + 31461893 = 31462402
641 + 31461761 = 31462402

Showing the first eight; more decompositions exist.
