Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555502, here are decompositions:

73 + 31555429 = 31555502
331 + 31555171 = 31555502
409 + 31555093 = 31555502
421 + 31555081 = 31555502
439 + 31555063 = 31555502
541 + 31554961 = 31555502
613 + 31554889 = 31555502
619 + 31554883 = 31555502

Showing the first eight; more decompositions exist.
